Abstract | Right triangles play a significant role in mathematics. In this favorite lesson, the authors help students understand variant and invariant properties by considering relationships among angle measures and side lengths in right triangles. Students explore these relationships using interactive mathematics software, changing one angle and observing the effect on the side lengths and other angles. Students observe that while some properties of the triangle vary, others remain constant, or "invariant". (ERIC). |
