Back

180°

Front

If one angle of a triangle measures 50° and another measures 55°, what is the measure of the third angle?

Back

Back

110°

Front

If a triangle has angles measuring 60° and 80°, what is the measure of the third angle?

Back

40°

Front

A triangle has angles measuring 45° and 45°. What is the measure of the third angle?

Back

90°

Front

In a triangle, if one angle measures 150°, what is the maximum possible measure of the other two angles?

Back

15° each (minimum) or 0° (not possible) for a triangle.

Front

What is the relationship between the angles of a triangle and the concept of supplementary angles?

Back

Two angles are supplementary if their sum is 180°, which is the case for the angles in a triangle.
