Students calculate the measures of angles/arcs formed by secants-tangents to circles that meet on the circle by find that measure in this matching card activity. One half of the 18 pairs of matching cards has a diagram of the circle/ tangent arc and the other half has the measures of those angles. Students work individually, in pairs or small groups to match the cards.
Also included are 12 additional cards which do not match to be uses in part or all for students who always finish early. Add a couple of extra cards to their set and give them a challenge.
You can also use the activity as a warm up, exit ticket , team competition, ticket in the door or one of the other activities described in my free resource.
