In this activity, students will use the triangle exterior angle theorem to solve problems.
#1 - 3 are simply numeric.
#4 - 9 require algebra to solve for x.
#10 - 15 require algebra for first solve for x, and
then find the missing angle measure.
Then, they will color the design by the colors listed next to their solutions!
Even my high schooler's like this activity. They refer to it as, "Color Therapy!"
