15. Let’s Measure Some Angles To measure angles, we use a Protractor

16. A Right Angle is 90°

17. An Acute Angle is less than 90°

18. Here are more acute angles- both less than 90 degrees.

19. An Obtuse Angle is more than 90°

20. Here are more obtuse angles- both more than 90 degrees.

21. Angles Can Face Different Directions This is a right Angle Here’s another And another And one more

22. What are each of these? Acute, or Obtuse angles? A D C B

23. What are these? A D C B Obtuse Acute
