- 1. corollary: this corollary states that a quadrilateral is a rhombus if and only if it has four congruent sides
- 4. this word describes shapes that curve inward
- 7. theorem: the segment joining the midpoints of two sides of a triangle is parallel to and half the length of the third side, what theorem is this?
- 10. postulate: this postulate states that through any given point not on a line there pases exactly one line parallel to that line in the same plane
- 11. angles: when angles have the same angle measure
- 12. postulate: this postulate states that if two angles form a linear pair, then they are supplementary
- 14. ratio: the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle
- 17. detachment: this is a way of using logic and geometry to determine if a statement is true based on statement given
- 18. vertices: the two endpoints of any side are called?
- 19. polygon: a polygon in where all the interior angles are less than 180 degrees
