Complete the Theorem:

"The sum of the measures of the two smallest sides of a triangle...

• ...will equal the measure of the third side.

• ...cannot be more than the measure of the third side.

• ...must be greater than the measure of the third side.

• ...has nothing to do with the third side.

Complete the Theorem:

"The sum of the angles of any triangle..."

• ...is equal to the measure of the third side.
