Solving for Angles

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

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

Back

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

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines on opposite sides of a transversal. They are equal in measure.

Front

What is the relationship between exterior angles and interior angles in a triangle?

Back

The exterior angle of a triangle is equal to the sum of the two opposite interior angles.

Front

If two angles are supplementary, what is their sum?

Back

The sum of two supplementary angles is 180 degrees.

Front

If two angles are complementary, what is their sum?

Back

The sum of two complementary angles is 90 degrees.

Front

What is the measure of an angle if it is vertical to a 43° angle?

Back

The measure of the vertical angle is also 43°.

Front

In a triangle, if one angle measures 95°, what can you conclude about the other two angles?

Back

The other two angles must sum to 85° since the total must equal 180°.

Front

What is the measure of an angle that is supplementary to a 22° angle?

Back

The measure of the supplementary angle is 158°.

Front

If two parallel lines are cut by a transversal, what can be said about the alternate exterior angles?

Back

The alternate exterior angles are equal.
