| Vertical | Angles opposite each other and congruent |
| Supplementary | angles that add to 180 degrees |
| Complementary | angles that add to 90 degrees |
| Alternate interior angles | Angles inside the parallel lines that are opposite sides of the transversal |
| Alternate exterior angles | angles outside the parallel lines that are opposite sides of the transversal |
| corresponding | angles on the same side of the transversal that are congruent |
| congruent | angles that have the same measure |
| parallel lines | two lines next to eachother that continue forever in both directions |
| transversal | a line that cuts two or more parallel lines |
| adjacent | two angles that share a side and a vertex |
| pythagorean theorem | the sum of the square of each leg is equal to the hypotenues squared |
| hypotenues | the longest side of a right triangle |
