**Parallel Lines & Transversals**

2
Transversal A line, ray, or segment that intersects 2 or more COPLANAR lines, rays, or segments. transversal transversal Parallel lines Non-Parallel lines

3
**INTERIOR –The space INSIDE the 2 lines**

EXTERIOR The space OUTSIDE the 2 lines exterior

**Special Angle Relationships**

Angles <3 & <6 <4 & <5 <3 & <5 <4 & <6 1 4 2 6 5 7 8 3 Angles <2 & <6 <3 & <7 <1 & <4 <6 & <7

8
**Special Angle Relationships WHEN THE LINES ARE PARALLEL**

♥Alternate Angles are CONGRUENT ♥Vertical Angles ♥Co-Interior Angles are SUPPLEMENTARY ♥Corresponding Angles are CONGRUENT 1 4 2 6 5 7 8 3 If the lines are not parallel, these angle relationships DO NOT EXIST.

**Let’s Practice m<1=120° Find all the remaining angle measures. 1 4**

6 5 7 8 3 m<1=120° Find all the remaining angle measures. 120° 60° 120° 60° 120° 60° 120° 60°
