Special Right Triangles - 30 60 90 and 45 45 90 Triangles

For a complete lesson on special right triangles, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn that in a 45-45 Access full lesson containing this video at: http://www.yourteacher.com/geometry/306090triangle.php Students learn that in a 45-45-90 triangle, the legs are congruent, and the length of the hypotenuse is equal to root 2 times the length of a leg. Students also learn that in a 30-60-90 triangle, the length of the long leg is equal to root 3 times the length of the short leg, and the length of the hypotenuse is equal to 2 times the length of the short leg. Students are then asked to find the lengths of missing sides of 45-45-90 and 30-60-90 triangles using these formulas. (more) (less)
