Students use their theorems of circles and tangent angles to find arc measures by solving for x. This is for students who have mastered the theorems and are looking for a challenge in solving for arc. Great practice in using equations as well.
Half the matching cards have the picture of a circle with arcs indentified, and the other half of the cards have the arc measures. Students will need to apply the theorems to set up the equations and then solve for x and plug back in equation to find the measure. Use with pairs or small groups or as a great station activity.
