This document defines and describes basic geometric figures including lines, angles, polygons, circles, arcs, and solids. It explains that a line is a set of points and can be straight, parallel, or perpendicular. An angle is formed by two rays with a common endpoint and can be a straight, right, acute, obtuse, complementary, or supplementary angle. Polygons are plane figures formed by three or more line segments, circles consist of all points equidistant from the center, and arcs are portions of a circle.
