Guided steps

Step 1 of 3

Count sides and vertices, then use those attributes to name or build the figure.

Studio challenge

A closed figure has 5 straight sides and 5 vertices. What is the name of this polygon?

Use the model and enter your response in the lesson answer field. The studio does not reveal the answer.
