Geometry Calculator LIGHT is a free app intended for math students, engineers and other people who need a fast way to compute numerical values involving geometric figures.

This app contains no ads!

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

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!

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