Geometry Term - Definition, Point - A location in space, represented by a dot., Line - A straight path that extends infinitely in both directions. It is defined by two points on the line., Line Segment - A part of a line that has two endpoints. It is the shortest distance between two points., Ray - A part of a line that has one endpoint and extends infinitely in one direction., Angle - The space between two intersecting lines or line segments, measured in degrees., Triangle - A polygon with three sides and three angles., Quadrilateral - A polygon with four sides and four angles., Square - A quadrilateral with four equal sides and four right angles., Rectangle - A quadrilateral with four right angles. Opposite sides are equal in length., Circle - A round shape with all points on the edge equidistant from the center., Diameter - A line segment that passes through the center of a circle, connecting two points on the edge., Radius - A line segment that connects the center of a circle to any point on the edge. It is half the length of the diameter., Perimeter - The total distance around the outside of a polygon. It is the sum of all the side lengths., Area - The measure of the space enclosed by a two-dimensional shape, usually expressed in square units., Volume - The measure of the space occupied by a three-dimensional shape, usually expressed in cubic units., Parallel Lines - Lines that are always the same distance apart and never intersect., Right Triangle - A triangle with one angle measuring 90 degrees., Congruent - Two shapes that have the same size and shape., Symmetry - A shape or object that can be divided into two identical halves when folded along a line., Polyhedron - A three-dimensional solid with flat faces, straight edges, and sharp corners.,
