1-38.

Nadine and Diondra were working together to divide a circle into three equal parts. They came up with the diagrams shown below. Tanisha said, *“One of these pictures is wrong.”* Homework Help ✎

What do you think? Is one picture incorrect? If so, which one? Why?

Try to imagine the separate pieces of a circle being rotated or moved.

Remember that dividing the circle into three equal parts means all three sections should be the same size.
