2. Angle, The amount of turning between lines meeting at a certain point.
3. Parallel, Line that are the same distance apart.
4. Perpendicular, Two lines that make a 90° angle
5. Adjacent angle, Angles next to each other.
6. Alternate exterior angle, opposite angle on outside.
7. Alternate interior angle, opposite angle in the inside.
8. Vertical angle, a pair of angles opposite of each other.
9. Acute angle ,Angle measuring less than 90°
10. Obtuse angle, angle more than 90°
11. Right angle, measuring 90°
