Derive and apply the formula for the area of a trapezoid. Please follow the steps below and answer the questions as you go along. Step 1: Fold the rectangle (index card) in half as pictured below to make a crease. Then unfold the rectangle. Step 2: Draw two points at the top of the rectangle. Connect each point to the closest endpoint of the fold (Not to the bottom of the RECTANGLE) Step 3: Cut along the two new creases formed (the two small triangles at the top of the rectangle) Step 4: Rotate the triangles 180° about the endpoints of the crease to create a trapezoid. The crease is called the MEDIAN because it is the line segment joining the midpoints of the nonparallel sides. Step 5: Discuss the questions below with your partner. Then answer the questions. How do the bases of the trapezoid relate to the original rectangle? How does the area of the rectangle relate to the area of the trapezoid? How can you find the median of the trapezoid? Step 6: What do you think is the formula for the area of a trapezoid? Area of a Trapezoid 10.1– Area of a trapezoid 10.1 Discovery Day 2
