This circuit is the same as the other beginning geometry circuit, but written at a higher level by my AP Calculus colleague Ginger Riddle. It introduces vocabulary such as vertical angles, supplementary, etc.
Your students will love to learn or review their definitions (vertical, complimentary, bisect, etc.) in the circuit format. Great for middle school, high school, or standardized test prep! Students work the first problem, then must hunt for their answer to advance in the circuit. Involves some algebra too (e.g. two angles are supplementary and both have variable expressions... so students must solve for "x" to advance in the circuit).
I have used this as review, guided notes, and independent practice, depending on the course. Can be turned into a scavenger hunt, task cards or I Have / Who Has?
No answer key included -- because the answers are part of the circuit. The teacher must work the circuit first before giving it to the students, but that is really all the prep needed!
