G is for Geometry

• The study of geometric figures in two dimensions (plane geometry) and three dimensions (solid geometry). It includes the study of points, lines,triangles, quadrilaterals, other polygons, circles, spheres, prisms, pyramids, cones, cylinders, and polyhedra. Geometry typically includes the study of axioms, theorems, and two-column proofs
