Supplementary angles
What is a trick to find corresponding angles?
What are the three parts of an angle?
2 rays and a vertex
What do we call an angle that is less than 90 degrees?
Acute
What do we call angles that are next to each other and that share a common vertex and a common ray?
Adjacent angles
What does alternate mean in alternate interior angles?
The other side of the transversal.
Wat is the symbol for an angle?

What do we call an angle on a straight line?
A straight angle
WHat do we call angles that form across from each other in an x?
Vertical angles
Which of these angle pairs are congruent: alternate interior, alternate exterior, vertical, complementary,adjacent and corresponding?
