1.  State the Angle Sum Theorem.

2.  State the Exterior Angle Theorem.

*Find the third interior angle if the other two angle measures are:

3.  75, 33

4.  45, 45

5.  105, 74

6.  57, 21

*Determine if the sum of the angles make a true triangle or not.

7.  93, 52, 35

8.  57, 91, 35

9.  60, 60, 60

10.  45, 45, 45

11.  115, 25, 40
 
 

*If the two remote interior angles equal "x" and "y", what is the measure of the extrior angle?

12. x = 35
      y = 47

13.  x = 78
       y = 38

14.  x = 29
       y = 63

15.  x = 74
       y = 31
