Shape Riddles

We have been studying 2-dimensional and 3-dimensional shapes.  Your child should know that 2D shapes have sides, corners, and angles.  3D shapes have edges, vertices, and faces.  On activity we did was find an shape in a bag to describe to the class.  The class then determined what the shape was by hearing the clues.  Today the class made WHO AM I? riddles.  Can you guess which shape is described in the riddles below?
