1. Transversal- A line that crosses across 2 more lines.
2. Angle- The amount of turning between 2 lines meeting at a point.
3. Parallel- 2 lines that will never intersect.
4. Perpendicular- All right angles to the horizon.
5. Adjacent angle- Angles immediately next to each other.
6. Alternate exterior angle- A pair of parallel lines.
7. Alternate interior angle- Is 1 angle.
