Parallel Lines & Transversals

Front

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

Back

Corresponding angles are equal.

Front

Define complementary angles.

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

If m∠TWX = 84°, what is m∠UVY if they are corresponding angles?

Back

m∠UVY = 84°.

Front

What is the definition of acute angles?

Back

Acute angles are angles that measure less than 90 degrees.

Front

What is the value of x if the angles are supplementary and one angle measures 80°?

Back

x = 100°.

Front

What are alternate interior angles?

Back

Alternate interior angles are equal when two parallel lines are cut by a transversal.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is 180 degrees.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect, and they are equal.

Front

If two angles are complementary and one angle measures 30°, what is the measure of the other angle?

Back

The other angle measures 60°.

Front
