Angles Vocab

What are corresponding angles?

• Angles whose sum measures 180 degrees

• Angles whose sum measures 90 degrees

• Two angles in the same position when parallel lines are cut by a transversal

• The angles opposite of each other when two lines cross.

What are interior angles?

• The angles inside of a shape

• The angles inside the triangle that are not adjacent to the exterior angle.

• Two angles whose sum measures 180 degrees.

• Two angles in the same position when parallel lines are cut by a transversal

What are alternate interior angles?

• A pair of angles on the outer side of two lines cut by a transversal, but on opposite sides of the transversal

• The angles opposite of each other when two lines cross

• A pair of angles on the inner side of two lines cut by a transversal, but on opposite sides of the transversal
