Samuel and Benjamin are studying geometry. They have a triangle and they know the measures of two of its angles. How can they find the measure of the third angle?

• The measure of the third angle is 180 degrees minus the sum of the two known angles.

• The measure of the third angle is the difference between the two known angles.

• The measure of the third angle is the sum of the two known angles.

• The measure of the third angle is half of the sum of the two known angles.
