This Problem Set is a part of the Lesson 8, Unit 1, Grade 6. To find the area of the given triangle, Diego and Jada used different strategies. Diego drew a line through the midpoints of the two longer sides, which decomposes the triangle into a trapezoid and a smaller triangle. He then rearranged the two shapes into a parallelogram. Jada made a copy of the triangle, rotated it, and lined it up against one side of the original triangle so that the two triangles make a parallelogram. Explain how Diego might use his parallelogram to find the area of the triangle.
