1. Transversal: a line that crosses two or more other lines.
2. Angle: the amount of turning between two lines that meet a common point.
3. Parallel: lines that are the same distance apart.
4. Perpendicular: two lines that intersect at a 90° right angle.
5. Adjacent angle: is next
6.alternate exterior angle: an angle formed outside a polygon when one side is extended.
7. Alternate interior angle: An angle with in a polygon.
8. Vertical angle: pair of angles opposite each other, formed by the intersection of straight angles
9.acute angle: less than 90°
10.obtuse angle: more than 90°
11.right angle: 90° right angle
Key:
Parallel: segment AB is parallel to segment CD
Vertical Angles: 1&3, 2&4, 5&7, 8&6
Adjacent Angle: 1 &2, 1&4, 2&3, 3&4, 5&6, 5&8, 6&7, 7&8
Transversal line: EF
Alternate exterior angle: 1&7, 4&6
Alternate interior angle: 2&8, 3&5
Acute angles: 2&4, 6&8
Obtuse Angle: 1&3, 5&7
Right Angle: none
