In this one-page assignment students find missing side lengths and angle measures of special right triangles. Every possible permutation from given to missing side is used, and problems include ones where students are given integers that they must both multiply and divide by radical expressions. When applicable students must rationalize the denominator. Correct answers decode a secret message, providing immediate feedback for the learner as this free math worksheet is self-checking.
