1. Parallel Lines cut by a transversal

2. Parallel lines cut by Transversal
A line passing through two or more other lines in a plane is called a transversal.
A transversal intersecting two parallel lines creates five different types of angle pairs.
corresponding angles
alternate interior angles
alternate exterior angles
vertical angles
linear pairs

3. 2 regions are formed

4. Corresponding Angles are congruent

5. Alternate Interior Angles are congruent

6. Alternate Exterior Angles are congruent

7. Vertical Angles are always congruent
a=d b=c e=h f=g

8. Linear Pairs are Supplementary
