About Geometry Pad
Geometry Pad is a dynamic geometry application for Android tablets with universal appeal. Teachers can use it in a geometry class for better students engagement and deeper understanding of geometric concepts. Students would benefit from using Geometry Pad while working on geometry assignments at home as well. Easily create complex geometric sketches, measure everything you have in your document, experiment with shapes and transformations.
Use following tools to sketch your geometry constructions (*):
- Move and scale. Scroll the workbook by your finger. Pinch and zoom the content of your workbook. Move and modify geometric shapes.
- Compass to create arcs.
- Point. Plot a point on the workbook. Customize point name and color.
- Line. Create a line. Customize line style, color and start/end points. Calculate line length (distance between points).
- Midpoint for lines. Show/hide midpoint for lines and polygon sides. Snap to midpoints.
- Parallel, perpendicular and tangent lines. The lines can be created as easily as regular lines. Just create and move the line until it automatically snaps to parallel, perpendicular or tangent.
- Angle. Create an angle with up to 1 degree precision. Customize angle line style and color.
- Triangle. Create a triangle of one of the predefined types: regular, right triangle, isosceles, equilateral. Customize sides style and color. Calculate triangle perimeter and area. Calculate inner angles of the triangle and length of its sides.
- Triangle lines. Create altitude, bisector and median lines in a triangle. Calculate length of triangle lines. Customize lines style and color.
- Quadrilateral. Create a quadrilateral of one of the predefined types: regular, square, rectangle, parallelogram, rhombus. Customize sides style and color. Calculate quadrilateral perimeter and area. Calculate inner angles of the quadrilateral and length of its sides.
- Circle. Create a circle. Calculate circle perimeter and area. Easily create circles inscribed into a triangle by placing circle's center close enough to the incenter of a triangle.
- Circle radius and chord. Create radius and chord lines for a circle. Customize lines style and color. Calculate the length of the lines.
- Polygons and regular polygons.
- Arcs and circular sectors.
- Ellipses.
- Text annotations. Create floating and pinned single and multiple lines text annotations. Customize text/background color and transparency.
- Measurements tool. Measure shape properties in single touch. Measure intersection points (line & line, line & circle). Use multitouch to measure distance between points and angle between lines.
- Transformation tools: rotation, reflection, enlargement and translation.
- Manual input of coordinates, lengths and angles. Use manual input to precisely locate points, setup custom length for a line or a polygon side, and change angle value.
- Built-in calculator: basic arithmetic functions, square root, sin, cos, tan.
Manage multiple documents with your geometric sketches at the same time using Save and Load features. In addition, you can share documents through e-mail or Dropbox.
Some of the tasks you can solve with Geometry Pad:
- Create geometric shapes and measure all its possible metrics like length, angle, area, perimeter, intersections, distance between points, angles between lines.
- Move/resize geometric shapes and watch how its metrics are changing in real time.
- Demonstrate circle theorems by creating and changing inscribed and center angles.
- Demonstrate theorems about incircles and excircles locations.
- Create and annotate complex geometric figures. Share them through export to image and e-mail features.

Can I use this to draw geometric patterns? If so, can you make a small video to demonstrate how to draw one that is basic. I can draw them but the apps that I have previously used were rather limiting. I have samples of my work and the type of patterns that I draw and your app seems to be the best choice for the job. Please help.

Just waisted 6 bucks is what i think, i cant even make a spiral with this app. Also I can't even download the actual app because I bought the plus in the free app so I guess that's another way this app screws you. I'm pretty pissed and I want my money back because I don't pay for apps that often and this looked promising but I highly doubt I'll get anything because it's aweful and that's the nicest way of putting it

You need to purchase it to use most of the functions, it shouldn't be in the free category.

I feel I am working with a graph and a pencil in my hand........Butt you should need to work it more precise, more handy, and easy to assessable. As when I was using magnify it was providing errors. Best of luck

Another crappy app you can't do anything without paying money. If your looking for an app that you can make your own floor plans or anything else run away from this app.

Hard to work with. Tools could be better like geoalgebra. Zoom does not reach far enough. Sharing as pic does not share the same pic you see on display. But there is also a lot of potential, hope it keeps improving.

Nice tool I thought. Alas, once you "Save As" you cannot find the file in your gallery app or file explorer. One feature needed Eben in a freebie version of the app as if this cannot be trusted to work, why would I want to pay for an unreliable full version???

Not polished. Could use outside QA and support. Buggy. Needs help docs and tutorials. No one like to make tutorials for their complex apps.

I like it, best I've tried so far. I like that it snaps to point, I don't. Like that when I add a polygon or shape that an adjustment of sides stays on screen blocking view of what I am creating.

It takes me FOREVER to make a drawing I need because I have to take the circles off the ends manually after every line, square, ect. If that gets fixed in the options menu for styles ill be very happy

Thank you for fixing the bug. It's a pleasure to have it back. However, some of the features originally in the free version is now only accessible in the paid version...

It's the only app I've found that comes close to supporting what I'm trying to do. (Mounting a solar panel to a shed wall so it points south and can be angled as the seasons change with consideration for roof line and door openings.). It has a lot of shortcomings but you can work around most of them. Hoping it would fix most of the shortcomings I spent $5.99 for the premium version. Bottom line: don't waste your money. The two versions are incompatible so I lost my previous work. (The"premium" version wouldn't install until I uninstalled the free version which deleted the saved files). None of the shortcomings are fixed and the additional features, except possibly being able to save as a PDF, are worth much. I'm going to keep the app just because nothing else I've found is as good as this. But I wish the developer would put more work into making it a good app.
