Front

What are adjacent angles?

Back

Adjacent angles are two angles that share a common side and a common vertex, but do not overlap.

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 complementary, what is the relationship between them?

Back

Two angles are complementary if the sum of their measures is 90 degrees.

Front

If two angles are supplementary, what is the relationship between them?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What is the measure of the third angle in a triangle if the other two angles are 45° and 75°?

Back

The measure of the third angle is 60°.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two lines.

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.

Front

What are same side interior angles?

Back

Same side interior angles are pairs of angles that are on the same side of the transversal and inside the two lines.

Front

What is the measure of angle b if it is given that angle a is 59° and they are supplementary?

Back

The measure of angle b is 31°.
