## How To Find Special Right Triangles

### A special right triangle is one which has sides or angles for which simple formulas exist making calculations easy. Of all these special right triangles, the two encountered most often are the 30 60 90 and the 45 45 90 triangles. For example, a speed square used by carpenters is a 45 45 90 triangle.

- This is a "Find Someone Who" activity in which students will practice finding missing sides in and special right triangles. There are 16 questions total The students must get up and trade papers with different people in the class to complete the activity.
- Special right triangles are the triangles that have some specific features which make the calculations easier. Of course, the most important special right triangle rule is that they need to have one right angle plus that extra feature. Generally, special right triangles may be divided into two groups:
