About Geometry Calculator
Geometry Calculator is a very useful tool for math students, engineers and other people who need a fast way to compute numerical values that involve geometric figures.
It currently has three sections:
1. Euclidean geometry in two dimensions: find side lengths, angles, area, perimeter, heights, circumference for:
- Right triangle, isosceles triangle, equilateral triangle, scalene triangle
- Rectangle, including Square
- Parallelogram, including Rhombus
- Trapezoid
- Regular polygons like pentagon, hexagon etc
- Circle
- Complex two-dimensional figure, constructed with points, segments and angles (BETA version)
2. Euclidean geometry in three dimensions: find surface areas, volumes etc:
- Sphere
- Right Cylinder and Slanted Cylinder
- Cone and Cone Frustum
- Prism, including Cube
- Regular pyramid
3. Coordinate geometry in two dimensions: find areas, distances, intersections:
- Straight line defined by two points
- Straight line and two different points (find on which side of the straight line they fall)
- Straight line and circle (intersection points)
- Circle, defined by center and radius
- Triangle, defined by three different points (area, centroid)
- Any convex quadrilateral, defined by four different points (area, centroid)
- Centroid (or center of mass) of a figure system
The app has both light theme and dark theme (changed automatically depeding on your phone settings).
Please let me know of you find any bugs in this app. Send me an email or leave a comment on the app blog. Thanks in advance!

User reviews
I downloaded this app for my 14 yo niece who struggles understanding geometry. She has taken a liking and plays with it every day for a few minutes.
