What are angles that have a sum of 90 degrees?

300
37 degrees
What is 53 degrees?
300
47 degrees
What is 133 degrees?
300

These angles are equal because they are across from each other. 

What are vertical angles?

300

angles are congruent because they are opposite from each other are also called this

What are vertical angles?

400

Supplementary angles

Angles that have a sum of 180 degrees
400
90 degrees
What is 90?
400

These angles are in the same location of different intersections. They are also congruent to each other. 

What are corresponding angles?

400
angles that are next to each other are called this
What is adjacent?
500

a linear pair

Supplementary angles that are also adjacent

500

These angles are on the inside of the parallel lines, but on opposite sides of the transversal. They are equal. 

What are alternate interior angles?

500
transversal
What is the line that cuts across parallel lines?
