In this problem, we're going to explain why any trapezoid that can be inscribed in a circle must be an isosceles trapezoid. in this figure, let's assume without loss of generality that segments ab and dc are parallel. by the end of this problem, we want to show that ∠d ≅ ∠c.
1. explain why ∠a must be supplementary to ∠d.
2. explain why ∠a must also be supplementary to ∠c.
3. now we know that ∠a is supplementary to ∠d and is also supplementary to ∠c. explain why that proves that ∠d must be congruent to ∠c.
