- 11. A segment connecting a vertex of a triangle to the midpoint of the opposite side
- 14. Describes lines, planes, or segments that intersect to form a perfect right angle (90°)
- 16. A transformation that changes the size of an object but not its shape
- 19. pair Two adjacent angles that share a common vertex and a common side, but whose non-common sides form a straight line
