| vertical angels | non-adjacent non-overlapping angles formed by two intersecting lines |
| adjacent angles | are two coplanar angles that share a vertex and a side but do not overlap |
| perpindicular | intersect to form two right angles |
| linear | nonshared rays form a straight angle |
| complements | two angles that add up to be 90 degrees |
| supplements | two angles that add up to be 180 degrees |
| linear pair property | the angles that form a linear pair are supplementary |
| vertical angles property | vertical angles congruent |
