This document defines and describes basic geometric shapes and terms. It explains that a point has no size, a line has two points and all points in between, and a plane is a flat surface that extends infinitely. It then defines angles, perpendicular and parallel lines, triangles, right triangles, polygons from 3 to 12 sides, squares, rectangles, trapezoids, parallelograms, circles, cylinders, spheres, arcs, and cones.

16. Circle A circle is A line forming a closed loop, every point on which is a fixed distance from a center point.

17. Cylinders A three-dimensional figure with two parallel congruent circular bases and a curved lateral surface that connect the bases

18. Sphere The set of points in space that are a fixed distance from a given point called the center of the sphere
