This document defines and describes basic geometric shapes including points, lines, planes, angles, triangles, quadrilaterals, circles, cylinders, spheres, and various three-dimensional polyhedra. Key properties are highlighted such as a point having no size, a line being a straight path that extends forever, a plane being a flat surface that extends forever, and circles and spheres having all points the same distance from the center. Common polygons like triangles, squares, rectangles, trapezoids, parallelograms are defined by their number of sides and internal angles. Three-dimensional shapes include cylinders with circular ends, spheres with a smooth curved surface, and polyhedra such as dodecahedrons, decahed
