When 2 parallel lines are both crossed by a transversal, these angles occupy the same position on the top and bottom parallel lines.
Corresponding Angles.
300
Linear Pair Angles
A pair of adjacent angles formed by intersecting lines. These angles are also supplementary.

300
If angle 2 is 90 degrees, what does angle 3 equal.
90 degrees.
400
What are vertical angles?
Congruent angles formed by two intersecting lines. These angles are located across from each other.
400
Alternate Exterior Angles
If two parallel lines are intersected by a transversal, these angles are located on the outside of the two parallel lines on opposite sides of the transversal.

Solve for x. 
x= 20
500
What are Alternate Interior Angles?
When 2 parallel lines are both intersected by a transversal these angles are inside of the two parallel lines and on opposite sides of the transversal.
500
Same-side Interior Angles
If two parallel lines are cut by a transversal, these angles are on the inside of the two parallel lines and on the same side of the transversal.
500
