1.2 Angle Relationships and Triangles

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

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

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

Back

Each angle in an equilateral triangle measures 60 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 is the measure of the missing angle if one angle is 50 degrees and the other is 90 degrees?

Back

The missing angle measures 40 degrees.

Front

How do you find the measure of an exterior angle of a triangle?

Back

The measure of an exterior angle is equal to the sum of the measures of the two opposite interior angles.

Front

What is the relationship between the angles in a right triangle?

Back

In a right triangle, one angle measures 90 degrees, and the sum of the other two angles is 90 degrees.

Front

If angle A measures 44 degrees, what is the measure of its complement?

Back

The complement of angle A is 46 degrees (90 - 44 = 46).

Front

If angle B measures 36 degrees, what is the measure of its supplement?

Back

The supplement of angle B is 144 degrees (180 - 36 = 144).
