In the Shape Factory, you created many shapes by rotating triangles about the midpoint of its sides. (Remember that the

**midpoint**is the point exactly halfway between the endpoints of the line segment.) However, what if you rotate a trapezoid instead?

*7-19 HW eTool*(Desmos). Homework Help ✎

Carefully draw the trapezoid above on graph paper, along with the given midpoints. Then rotate the trapezoid

Rotating about the midpoint of the base forms a hexagon (one convex and one non-convex).

Rotating the trapezoid about the midpoint of either of the non-base sides forms a parallelogram.

Use the eTool below to rotate the figure and test your answer.
