Geometry

2. A polygon with four sides and four angles.
5. A figure formed by two rays or line segments with a common endpoint called the vertex.
6. A location in space with no size, usually represented by a dot.
8. A straight path of points that extends infinitely in both directions.
10. Segment: A part of a line consisting of two endpoints and all the points between them.
13. The set of all points in a plane that are equidistant from a given point called the center.
14. The distance around the boundary of a two-dimensional shape.

1. A polygon with three sides and three angles.
3. A part of a line that starts at one endpoint and extends infinitely in one direction.
4. A line segment with one endpoint at the center of a circle and the other endpoint on the circle.
6. Lines: Lines that intersect at a right angle (90 degrees).
7. Lines: Lines that are always the same distance apart and never intersect.
9. A line segment that passes through the center of a circle and has endpoints on the circle.
11. The measure of the space enclosed by a three-dimensional shape.
12. The measure of the surface enclosed by a two-dimensional shape.
