Hands-On Trigonometry Proof

This set contains four separate “proofs” of trigonometry relations with examples of 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.

These are not rigorous mathematical proofs, but rather visual common-sense proofs.

As such, they help make these abstract relationships real and believable.

By actually handling the pieces, students engage their minds to a greater degree than they would by merely looking at the proofs on paper.

The color instructions describe how each proof is demonstrated and four reproducible worksheets reinforce the material.
