This activity is a great review activity, some problems involve solving for the variable, others an angle measure. The students can start on any card, the answers will loop back to the first card, 12 problems total.

The following Theorems are used:

Isosceles Triangle Theorem

Exterior Angle Theorem (2 problems)

Alternate Interior Angle Theorem (2 problems)

Triangle Angle Sum Theorem

Corresponding Angles Theorem

Linear Pair Theorem

Same Side Interior Angles Theorem

Vertical Angles Theorem combined with Isosceles Triangle Theorem

Triangle Angle Sum with a Perpendicular angle combined with Vertical Angles Theorem

Linear Pair, Triangle Angle Sum, Perpendicular Angle Theorems combined in one problem

A blank worksheet is included for the students to show their work.
