- When parallel lines are intersected by a transversal line, they form 5 special angle pairs.
- ALTERNATE INTERIOR ANGLES
- Angles that are between parallel lines and on opposite sides of the transversal
- *They are congruent*
- ALTERNATE EXTERIOR ANGLES
- Angles that are outside parallel lines and on opposite sides of the transversal
- *They are congruent*
- CONSECUTIVE (SAME SIDE) INTERIOR ANGLES
- Angles that are between parallel lines and on the same side of the transversal
- *They are supplementary*
- CONSECUTIVE (SAME SIDE) EXTERIOR ANGLES
- Angles that are outside parallel lines and on the same side of the transversal
- *They are supplementary*
- CORRESPONDING ANGLES
- Angles that are in the same relative position
- *They are congruent*
