4. Parallel Lines and Transversals
Lines that will never intersect because they are going the exact same direction
Symbol:
Transversal:
A line that intersects a set of parallel lines

5. Vertical
Angles directly across the vertex (diagonal to each other)

6. Adjacent
Angles that share a common side (next to each other)

7. Corresponding
Angles in the exact same position on each parallel line

8. Interior
Angles in between the parallel lines or inside of the figure

9. Exterior
Angles outside of the figure or not enclosed in the parallel lines

10. Consecutive
