Guided Proof of Law of Cosines
An enrichment activity for advanced classes or students needing a challenge. A two-column proof of the Law of Cosines, using right triangle trigonometry, is provided for the teacher. On the student handout, the steps are present, but out of order. Students are asked to cut the steps out and the re-arrange them into a logical sequence. A teacher could ask for a written or spoken explanation of why the steps work if desired.

You may use this activity to challenge yourself to show the equivalence of the “collapsible compass” with the “modern compass,” or challenge your m
