WebIn Problems 21 and 22, prove each part of the third trapezoid theorem: A trapezoid is isosceles if and only if its diagonals are congruent. Use the first two trapezoid theorems, which were proven in Problems 19 and 20. 21. Prove that if a trapezoid is isosceles, then its diagonals are congruent, which is the first part of the theorem.

Trapezoid Bases, Legs, Angles and Area, The Rules and Formulas

WebThe area of the trapezoid is a(b + c) / 2. Take the trapezoid ( − 2, 0), (2, 0), (1, 1), ( − 1, 1). This has area 3 and diagonal √10. If a = b + c, the area would be a2 2 = 5 instead of 3. An easy way to see it is to imagine a very wide trapezoid. b and c will be almost vertical and no longer than the height, but the diagonal a is very long.
