This document contains geometry formulas for calculating the areas and perimeters of various shapes including triangles, squares, parallelograms, trapezoids, rhombuses, circles, rectangular solids, cubes, cylinders, and polygons. It also includes formulas for coordinate geometry such as distance, mid-point, slope, and the general linear form.
