GEOMETRIC CHARACTERISTICS OF A SECTION is an Android application that helps determine the properties of polygonal sections. This app requires the input of the (x,y) coordinates of the vertices of the polygon, which must be located entirely within the first quadrant, and must be input sequentially for a complete clockwise path around the polygon. It also allows the deletion of holes in the cross-section, which do not intersect the boundary, by following a counter-clockwise path.

The app is designed to calculate the properties of polygonal sections with ease. It is an excellent tool for students and professionals who work with polygonal sections. The app is free, and it is compatible with Android 9.0.
