Angle Pairs
We use this word for two angles that add up to 90 degrees.
What is complementary?
This kind of shape goes forever in one direction.
What is a ray?
2x + 6 = 20
What is x = 7?
The distance between (0,0) and (6,0).
What is 6?
This is how we indicate two line segments are congruent on a diagram.
What are tick marks?
When two lines intersect, these are the angles "across" from each other.
What are vertical angles?
We use this kind of letter to represent a point.
What is a capital (block or non-script) letter?

What is x = 13?
The midpoint of the line segment with endpoints (1,5) and (1,9).
What is (1,7)?
What is 89?
The name for a ray or line that divides an angle into two congruent angles.
What is an angle bisector?
The kind of shape formed when two planes intersect.

The distance between the points (5,2) and (2,6).
What is 5?
This is the angle measure of the smallest angle when a right angle is bisected and then bisected again.
What is 22.5?
Two angles that are on the same side of a transversal and outside the parallel lines.
What are consecutive exterior angles?
If line segment AB is 9 cm and line segment BC is 11 cm, this is the shortest possible length of line segment AC.
