1. Transversal-a line that intersects two other lines.
2. Angle-the amount between two lines at a common point.
3. Parallel-two lines that are the same distance apart from each other.
4. Perpendicular-right angles toured the horizon.
5. Adjacent angle-is right next to.
6. Alternate exterior angle-angles are ought side of the parallel lines opposite of the transversal.
7. Alternate interior angle-angels are inside the parallel lines opposite of the transversal.
8. Vertical angle-pair of angles opposite of each other, formed by intersection of straight lines.
9. Acute angle-angle measuring less then 90 degrees.
10. Obtuse angle-any angle somewhere between 90 and 180 degrees.
11. Right angle-an angle measuring a perfect 90 degrees.
Key:
1. Parallel lines:2
2. Transversal line: line segment BE.
3. adjacent angle:1&2,2&3,3&4,4&1,5&6,6&7,7&8,8&5.
4. Alternate exterior angle: 1&7, 4&6.
5. alternate interior angle:2&8,3&5.
6. vertical angle: none
7. acute angle:4
8. obtuse angle:4
9. right angles, if any:none
