This set contains four separate "proofs" of trigonometric relations, with examples of a Pythagorean identity, a sum formula, a double-angle formula, and two sum-to-product formulas.

Demonstration of each relation is accomplished by physically rearranging the pieces to establish equalities of areas or lengths.

This visual approach helps to make these abstract relationships more visual and understandable to students.

The Hands-On Trigonometry Proofs set includes color instructions, reproducible worksheets, and 20 magnetic foam pieces!
