While working on the quadrilateral hotline, Jo Beth got this call: “I need help identifying the shape of the quadrilateral flowerbed in front of my apartment. Because a shrub covers one side, I can only see three sides of the flowerbed. However, of the three sides I can see, two are parallel and all three are congruent. What are the possible shapes of my flowerbed?” Help Jo Beth answer the caller’s question.
Draw a diagram that depicts Jo Beth's description.
It could be a square, which means it MUST be another type of quadrilateral.
