1. Your mission: With your group, you need to come up with a poster that presents the information in your section What you need: All vocabulary All Area formulas All theorems An example problem – DO NOT PICK A PROBLEM THAT IS DONE FOR YOU! WORK OUT ONE OF THE HW PROBLEMS! You have 20-25 minutes to complete the poster. You will present the poster to your class. Each person must present a piece of the poster. I will give you a class participation grade on your effort, correct information, group participation, and presentation.

2. 11.3 The Area of a Trapeziod b2b2 b1b1 h

3. T102: The area of a trapezoid equals one-half the product of the height and the sum of the bases. A trap = h(b 1 + b 2 ) Where b 1 is the length of one base, b 2 is the length of the other base, and h is the height.

4. Median of a Trapezoid The line segment joining the midpoints of the non-parallel sides of a trapezoid is called the median of the trapezoid. CL Z U X E Y

5. T103: The measure of the median of a trapezoid equals the average of the measures of the bases. M = (b 1 + b 2 ) Where b 1 is the length of one base and b 2 is the length of the other base.

6. T104: The area of a trapezoid is the product of the median and the height. A trap = Mh Where M is the length of the median and h is the height.

9. 8x2x 5x 4x Find the height and the perimeter of this trapezoid if its area is 245m 2.

10. Height = 49 Perimeter = 20(12.25) = 245 Perimeter = 20(12.25) = 245
