  • Theorem 3-8 states that if the measures of two supplementary angles are in the ratio 7:3, then the angles are congruent. To prove this theorem, we can begin by saying that two angles are supplementary if their measures add to 180 degrees. Since the given angles have a ratio of 7:3, then the sum of their measures must be equal to 10. Since the sum of any two supplementary angles must always equal 180 degrees, we can conclude that 10 = 180, thus showing the angles are congruent and the theorem is proven.
