Name

3. Can an angle greater than 90° have a complement? A supplement? Explain.

Answer Key: Exit Ticket

Complementary and Supplementary Angles

Complement 90 − 47 = 43°; supplement 180 − 47 = 133°
2(30) + 10 = 70; 90 − 70 = 20°
No complement (it's already more than 90°), but yes, a supplement, as long as it's less than 180°.

Quick read: 70° on #2 means the student evaluated the expression but forgot to find its complement. Hole-In-One Hero mode practices exactly this.
