Solve It! Draw a trapezoid on a sheet of graph paper. Label its bases b₁ and b₂. Draw its midsegment. Cut out the trapezoid, and then cut it along the midsegment. Rotate the top part of the trapezoid 180° so that b₁ and b₂ now form one long base. How can you use this new figure to find the area of a trapezoid? Explain your reasoning?
