• Linear Pair

• Vertical Angles

Angles 1 and 3 are what angle pair?

• Complementary

• Supplementary

• Adjacent

• Vertical

Angles 4 and 1 are what angle pair?

• Complementary

• Linear Pair

• Acute

• Vertical

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 is a transversal?

• A line that intersects two or more lines

• The angles opposite of each other when two lines cross

• Two angles whose sum measures 180 degrees

• Lines that intersect to form a 90 degree angle

What are alternate exterior 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

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

What are vertical angles?

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

• The angles opposite of each other when two lines cross

• The angles inside of a shape

• Two angles whose sum measures  90 degrees
