Geometry is a free geometric calculator developed by ARPAplus for Android devices. It is a comprehensive tool for calculating plane and solid figures. The app offers formulas and solutions based on user input data for shapes like triangle, square, rectangle, parallelogram, rhombus, trapezoid, polygon, circle, ellipse, sphere, cube, box, cylinder, cone, truncated cone, prism, pyramid, truncated pyramid, and the octahedron.

The app is divided into two sections: Planimetrics and Solid Geometry. The Planimetrics section includes calculations for shapes in two dimensions, such as the perimeter, area, and angles of triangles, squares, rectangles, and circles. The Solid Geometry section includes calculations for shapes in three dimensions, such as the volume, area, and lateral surface of spheres, cubes, cylinders, cones, pyramids, and prisms. The app provides accurate and reliable solutions for all the shapes it covers.

Geometry is a useful tool for students, teachers, and professionals who need to perform geometric calculations on a regular basis. It is easy to use, and the user interface is simple and intuitive. Overall, it is a great app for anyone who needs to calculate geometric figures quickly and accurately.
