1. Transversal- A line that crosses two or more line
2. Angle- Amount of a turning between two lines that meet at common points
3. Parallel- Lines that never intersected and are the same distance apart
4. Perpendicular- Two lines that intersected at a 90° angles
5. Adjacent Angle- Angles that are right next to each other
6. Alternate Exterior Angle- Angles that are the outside and biggest angles on the parallel lines and are horizontal to each other along the transversal
7. Alternate Interior Angle- Angles that are inside and smaller angles on the parallel lines and horizontal to each other along the transversal
8. Vertical Angle- Pair of angles opposite to each other made on the intersection of straight lines
9. Acute Angle- A angle that is smaller than 90°
10. Obtuse Angle- A angle that is bigger than 90° and 180°
11. Right Angle- A angle that measures 90° exactly
Key:
1. Parallel Lines: line segments A & B , C & D
2. Transversal Line: E & F
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:1 & 3, 2 & 4
7. Acute Angle: 2,4, 6,8
8. Obtuse Angle: 1,3,5,7
9. Right Angles: None
