8. The total length of the sides of a polygon.
10. A statement that has been proven to be true based on previously established facts.
11. Figures that have the same shape and size.
14. A statement that is accepted without proof as a basic truth.
17. ANGLE An angle that measures more than 90 degrees but less than 180 degrees.
18. A quadrilateral with two pairs of adjacent sides that are equal in length.
19. A flat, two-dimensional surface that extends infinitely in all directions.
20. A figure formed by two rays with a common endpoint.
22. The perpendicular distance from a vertex of a triangle to the line containing the opposite side.
23. A straight path that extends infinitely in both directions.
