Exterior Angle Theorem Matching Card Theorem
Students practice finding the exterior angle of a triangle by using the Exterior Angle Theorem. 18 pairs of matching cards- one half the cards has a detailed diagram of a triangle with the angle measurement desired and the other half of the cards have a measurement.

Students can work in pairs, small groups to match up and explain their answers to each other.

Bonus pages: For students who need a little extra challenge , or as an introduction to a more difficult activity students have a set of 10 matching cards where students just need to solve for x to match up cards. Half the cards have the diagram and the other half have the x value. Great for differentiating in the classroom.
