The height of the parallelogram is 8 √2, so the area of the parallelogram is 48 square units. [Check out the special right triangle section here if you can't get the height fast.] Let YZ of the trapezoid be x and draw the height. Using 45-45-90 degree angle ratio, you'll get the height. 4.1 Worksheet Triangle Sum and Exterior Angle Theorem Answer Key NO WORK, NO CREDIT! 1. 75 2. 63 3. 20 4. 55 5. 23 6. 17 7. 85 8. 30 9.
