| A | B |
|---|
| angles on the same line | supplementarry |
| angles whose sum totals 90 degrees | complentary |
| angles that share a common side | adjacent |
| means on opposite side of transversa | alternate |
| line that intersects 2 lines at two different points | transversal |
| angles that total 180 degrees | supplementary |
| angles that are opposite of each other | vertical |
| angles that are on exterior and opposite sides of transversal | alternate exterior |
| angles that are on opposite sides of tranversal and are in interior | alternate interior |
| angles that are on same side and interior of transversal | consecutive interior |
| angles that are on same side or transversal in which one angle lies in interior and other angle lies in exterior | corresponding |
| when 2 angles are equal | congruent |
| if one vertical angle equals 30 degrees, the other vertical angle equals | 30 degrees |
| if one supplementary angle equals 80 degrees, the other supplementary angle equals | 100 degrees |
| adjacent angles share the same | side |
| if one consecutive interior angle equals 70 degrees, the other supplementary angle equals | 110 degrees |
| If one alternative exterior angle equals 40 degrees, the other alternative exterior angle equals | 40 degrees |
| Cuts an angle in half | angle bisector |
| If one corresponding angle equals 50 degrees, the other corresponding angle equals | 50 degrees |
| the non common sides of supplementary angles form a | line |
