Geometry Pad+ is identical to Geometry Pad with premium features already integrated into the bundle. It is perfect for educational institutions because it supports volume purchase program with a big discount if you buy more than certain number of copies. If you are using Geometry Pad in a classroom and you need premium features then Geometry Pad+ is your choice.
Can I use volume purchase program to buy Geometry Pad?
Volume purchase program is only available for Geometry Pad+. Please note that we have a significant discount if you buy more than certain number of copies.
What is the Premium Features Pack and why would I buy it?
The Premium Features Pack is a set of premium features that are unlocked through an in-app purchase. The premium features include parallel, perpendicular and tangent lines; midpoint; persistent snapping; and persistent measurement windows. The list of premium features will grow in future updates and new features will be added free of charge if you bought the original package. To buy the Premium Features Pack tap the “Go Premium” button, review the features description and price, and click the Buy button when you are ready to make the transaction.
Premium Features Pack is not just some additional features you can use today, it is also an investment. Geometry Pad is usually updated at least once per month. Each update will bring new features to the Premium Pack. And the price will increase as we add more and more features. Buying it now you are getting all these future improvements for free.
What features are included into the Premium Features Pack?
Premium Features Pack unlocks following features:
- parallel, perpendicular and tangent lines,
- persistent snapping and persistent measurement windows,
- manual input for coordinates, length and angle value,
- built-in calculator,
- transformations: rotation, reflection, enlargement and translation,
- work with line intersections: create intersection as a new point, display intersection angles, remove intersection,
- regular polygons: create regular polygon and modify number of vertices on the fly,
- ellipses, arcs and circular sectors.
Can I use Geometry Pad in a classroom?
If you don't need premium features then yes, feel free to use Geometry Pad in a classroom. However, if you need premium features then you need to use Geometry Pad+ instead.
How do I input a custom value for a point or vertex coordinate?
Please activate the Edit tool by tapping the pencil icon. Now you can tap any point or vertex and change its coordinates using the built-in numpad/calculator.
How do I change the length of a line or polygon side?
Please activate the Edit tool by tapping the pencil icon. Now you can tap any line or polygon side and change its length using the built-in numpad/calculator.
How do I input a custom value for an angle?
Please activate the Edit tool by tapping the pencil icon. Now you can tap any angle and change its value using the built-in numpad/calculator.
How do I rotate a geometric shape?
You can rotate a single shape by using multy touch. Just hold any point on the shape that needs to be the rotation center. At the same time tap and start moving second point anywhere on the screen. By moving the second point you are defining the rotation angle.
How do I apply a rotation transformation for the document?
Activate the rotation tool. A rotation control would appear on the screen. Drag the center of the control to set the center of the rotation transformation. Next, drag the point on the rotation control circle to define the rotation angle.
How do I apply a reflection transformation for the document?
Activate the reflection tool. A line with Flip button would appear on the screen. Move the line to define the axis of reflection. Next, press the Flip button to complete the reflection.
How do I apply a translation transformation for the document?
Activate the translation tool. Now just tap and drag any point on the screen to start the translation. The shapes would be translated for an integer number of units if you have the Snap to Grid option on. If the option is off then shapes would be translated for a non integer number of units.
How do I use the built-in calculator?
You can use built-in calculator in two scenarios: when you use the Edit tool and when you activate the Calculator tool from the bottom menu.
How do I create an intersection of two lines or a line and a circle?
The intersection is detected automatically and you can use it right away without creating additional objects. For example, you can snap to intersections by just moving a point close enough. Or you can measure an intersection (coordinates and angle) by tapping it when the Measurements tool is active.
You can get even more for lines intersections. Just tap the intersection and select Create Intersection in the popover menu. A new point will be created at the intersection with all intersection angles displayed. Tap the point again to modify its properties or to remove it.
Snapping is used to precisely locate objects either in relation to the coordinate grid or to other objects. For example you can move the end point of one line close enough to the midpoint of an another one and it automatically snaps to the midpoint. A point can snap to another point, to a line or to a circle. It also snaps to the intersections of the grid lines. Snapping also comes into play when you create parallel, perpendicular and tangent lines. You can turn on/off different kind of snapping in the snapping menu.
Persistent snapping means that the objects remain snapped or relationally oriented to each other even after the target object is moved or changed. The target object is the object you snapped to. It is usually created first. The dependent object is the another object in the pair. For example if you snapped line AB to the midpoint of line CD then CD is the target object and AB is the dependent object. AB stays snapped to the midpoint of CD even if you move or resize CD. But it doesn’t if you move AB instead. Persistent snapping works the same way for perpendicular and parallel lines.
What is persistent measurements window?
You can see the measurements window when you activate the measurements tool and tap a geometric shape. The window normally closes if you tap a different shape or activate a different tool. But you can make it persistent (always visible) if you tap the pin icon in the upper right corner of the window. The measurements in the persistent measurements window are automatically updated when you change the shape it is associated with.
How can I create parallel lines?
Creating a parallel line is very similar to creating a regular line. Just start creating a second line and move it close enough to become parallel to the first line. The line snaps to become parallel automatically. The parallel marks (double arrows) are displayed on both of the lines when parallel snapping has been triggered.
How can I create perpendicular lines?
Creating a perpendicular line is similar to creating a parallel line. Just start creating a second line and move it close enough to become perpendicular to the first line. The line snaps to become perpendicular automatically. The right angle mark is displayed between the lines when perpendicular snapping has been triggered.
How can I create a tangent line?
Creating a tangent line is similar to creating a regular line. Just start creating a line and move it close enough to become a tangent to the given circle. The line snaps to the tangent line automatically.
To duplicate a shape just long tap the shape and select Duplicate in the popover menu.
How can I transform a specific shape or copy shapes while transforming?
You can customize a transformation by pressing the Settings button displayed right below the top bar. You can choose what objects to transform. You can also turn on the Copy Objects option. That way the copies of the shapes will be created and transformed instead of the objects themselves.
How can I fill a shape with a color?
Tap the shape and select the Fill property in the popover window. Now you can modify the level of translucency of the shape.
How can I create a midpoint for a segment?
Tap the line and find “Show midpoint” property in the properties popup. Turn the property on. The midpoint becomes visible for the line. Turn the property off if you don’t need the midpoint anymore. You can edit midpoint properties in the line properties window. Just open the window, locate and select Midpoint entry and change one of the available properties: Show Coordinates or Name.
