Triangle Sum Theorem

Front

What is the Triangle Sum Theorem?

Back

The Triangle Sum Theorem states that the sum of the interior angles of a triangle is always 180 degrees.

Front

If one angle in a triangle is 90°, what type of triangle is it?

Back

It is a right triangle.

If the angles of a triangle are represented as x, y, and z, what equation represents the Triangle Sum Theorem?

Back

x + y + z = 180°

What is the measure of the third angle in a triangle if the other two angles are 98° and 82°?

Back

0° (not a valid triangle).
