WebSum of the measures of two angles = 75° + 60° = 135°. Using the properties of a triangle, we know that the sum of all three angles of triangle = 180°. Therefore, the measure of the third angle = 180° - 135° = 45°. Example 2: Tim wants to construct a triangle with the lengths of sides 5 cm, 4 cm, and 9 cm.
