1. transversal- a line that intersects two other lines.
2. angle-the amount of turning between two lines meeting.
3. parallel-lines that are the equal distance apart.
4. perpendicular-right angles to the given point.
5. adjacent angle-angles that are right next to each other.
6. alternate exterior angle-transversal angles on a line.
7. alternate interior angle-transversal angles turned inward.
8. vertical angle-pair of angles opposite from each other.
9. acute angle-an angle less than 90 degrees.
10. obtuse angle-angle between 90 and 180 degrees
11. right angle-and angle that’s 90 degrees
KEY:
1. parallel lines: line segments AB & CD
2. transversal line: line segment EF
3. adjacent angles: 1&2, 2&3, 3&4, 4&1, 6&7, 5&8, 5&6, 7&8
4. alternate exterior angles:1&7, 6&4
5. alternate interior angles:3&5, 2&8
6. vertical angles:1&3, 5&7
7. acute angles:2, 4, 6, 8
8. obtuse angles:1, 3, 5, 7
9. right angles, if any: none
