Parallel Lines and Transversals

Front

What is the Angle Relationship when two lines are crossed by a transversal?

Back

Vertical angles are formed when two lines intersect, and they are equal.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What are complementary angles?

Back

Two angles that add up to 90 degrees.

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal.

Front

Identify a pair of corresponding angles: ∠4 and ∠3, ∠4 and ∠1, ∠4 and ∠2, ∠4 and ∠8.

Back

∠4 and ∠8 are corresponding angles.

Front

If angle S and angle B are supplementary, what is their relationship?

Back

Angle S and angle B add up to 180 degrees.

Front

What is the relationship between alternate interior angles when two parallel lines are cut by a transversal?

Back

Alternate interior angles are equal.

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

If two angles are vertical angles, what can be said about their measures?

Back

Vertical angles are equal in measure.

Front

If angle A is 70 degrees, what is the measure of its supplementary angle?

Back

The supplementary angle is 110 degrees.
