1.transversal-a line that goes thought at lease two lines
2.angle-the amount of turning from a common point
3. parallel- two lines that never meet
4. perpendicular-two pairs of line that mean at a right angle
5. adjacent angle- side that are right next to each other
6. Alternate exterior angle-a pair of line intersected by a transversal.
7. Alternate interior angle- a pair of line intersected by a transversal.
8. vertical angle- pair of angle opposite of each other
9. acute angle- a measurement less that 90° degrees
10. obtuse angle- a measurement greater than 90° degrees
11. right angle- a measurement that is 90° degrees
