Angle Relationships

Front

What are Alternate Exterior Angles?

Back

Angles that are on opposite sides of a transversal and outside the two lines it intersects.

Front

What are Corresponding Angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal.

Front

What are Vertical Angles?

Back

Angles that are opposite each other when two lines intersect; they are always congruent.

Front

If angle P measures 60 degrees, what is the measure of angle C if they are supplementary?

Back

120 degrees.

Front

If angle A and angle B are complementary and angle A measures 30 degrees, what is the measure of angle B?

Back

60 degrees.

Front

What is the relationship of angles formed by a transversal cutting through two parallel lines?

Back

They create corresponding, alternate interior, alternate exterior, and same side interior angles.

Front

What are Same Side Interior Angles?

Back

Angles that are on the same side of the transversal and between the two lines.

Front

If angle 5 is 45 degrees, what is the measure of angle 6 if they are vertical angles?

Back

45 degrees.

Front

What is the sum of the measures of angles in a triangle?

Back

180 degrees.

Front

If angle X is 70 degrees, what is the measure of its complement?

Back

20 degrees.
