MISSING ANGLES!

Front

What are vertical angles?

Back

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

Front

What is the measure of each angle in an equilateral triangle?

Back

Each angle in an equilateral triangle measures 60 degrees.

Front

What are complementary angles?

Back

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

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What are corresponding angles?

Back

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

Front

What are alternate interior angles?

Back

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

Front

If one angle measures 40 degrees, what is the measure of its complementary angle?

Back

The complementary angle measures 50 degrees.

Front

If one angle measures 130 degrees, what is the measure of its supplementary angle?

Back

The supplementary angle measures 50 degrees.

Front

What is the relationship between vertical angles?

Back

Vertical angles are always equal to each other.

Front

How do you find the measure of a missing angle in a triangle?

Back

To find the missing angle in a triangle, subtract the sum of the known angles from 180 degrees.
