2. Write a statement about the sum of the interior angles of a triangle below: The sum of all the interior angle in a triangle is 180 o <A + <B + <C = 180 o

3.  If you know the measures of two angles in a triangle, you can calculate the measure of the third 60 o 70 o A B C <A + <B + <C = 180 o 60 o + 70 o + <C = 180 o 130 o + <C = 180 o <C = 180 o – 130 o <C = 50 o

4.  Find the measure of the missing angle 42 o 65 o

5.  Find the measure of the missing angle 31 o

6.  Find the measure of the missing angle
