Skill Practice!

Determine which angle has the greatest measure.
1. ∠1, ∠3, ∠4 2. ∠4, ∠5, ∠7

3. ∠2, ∠3, ∠6 4. ∠5, ∠6, ∠8

Use the Exterior Angle Inequality Theorem to list all angles that satisfy the stated condition.

5. all angles whose measures are less than m∠1

6. all angles whose measures are less than m∠9

7. all angles whose measures are greater than m∠5

8. all angles whose measures are greater than m∠8

Determine the relationship between the measures of the given angles.

9. m∠ABD, m∠BAD 10. m∠ADB, m∠BAD

11. m∠BCD, m∠CDB 12. m∠CBD, m∠CDB

Determine the relationship between the lengths of the given sides.
