LESSON 4 Measuring and Estimating Angles

Estimating Angles

Mrs. Dewey drew two angles and wrote five angle measures on the board. She asked the class to choose the best estimates for the size of ∠X and ∠Y.

1. Linda decided the best estimate for ∠X is 100°.

         Do you agree with Linda? Why or why not?

2. John and Keenya had different estimates for ∠Y. John estimated 60° and Keenya estimated 85°. Which do you think is a better estimate? Explain your choice.
