Trapezoids Solutions
1. The parallel sides of a trapezoid cannot be congruent because this would make the
figure a parallelogram.
2. ! = 33
3. ! = 28
4. ! = 8
5. ! = 11
6. ! = 37
7. ! = 5
8. ! = 4
9. Distance of !" ≈ 6.71 and the distance of !" ≈ 7.07. Because the diagonals are not
congruent, the figure is not an isosceles trapezoid.
10. Distance of !" ≈ 9.49 and the distance of !" ≈ 9.49. Because the diagonals are
congruent, the figure is an isosceles trapezoid.
14. The opposite angles in an isosceles trapezoid are supplementary.
15. Trapezoids are quadrilaterals with exactly one set of parallel sides.
