Geometry calculates geometric figures such as spheres, triangles, cones, trapezoids, circles and cylinders. Also, it has an application in engineering to calculate the flow and geometry in an open trapezoid channel. You can calculate the area, volume or perimeter of a: Square Trapezoid Sphere Circle Cone Calculate the geometry of an open channel (engineering-hydraulic) Trapezoid Rectangle Triangle Application Features: Enhance OS 5 Free upgrades Help Docs Enhance security
