Geometry Calculator PRO

Solve triangle, parallelogram, prism, pyramid and many more! Get step by step solutions and theory hints!

Geometry Calculator PRO 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)

*For all types of triangles, the law of sines is used.

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 (analytic) 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

You'll notice a canvas at the top of each page. That is where geometric figures are drawn after you input numerical values, to help you better understand the problem you're trying to solve!

Some sections also provide a step-by-step symbolic and numerical solution.

You can also keep the result (figure + computed values) as a .png image, for later reference, by clicking on the "Save Screenshot" link at the bottom of each page.

You can also check your understanding of any particular figure by taking the quiz found on its corresponding page!

The app has both light theme and dark theme (changed automatically depending on your phone settings).
