In this lesson our instructor talks about special right triangles. First she talks about the 45-45-90 triangles and does some examples. The she discusses the 30-60-90 triangles and does some examples. Four complete extra example videos round up this lesson.
In a 45°-45°-90° triangle, the hypotenuse is times as long as the leg
In a 30°-60°-90° triangle, the hypotenuse is twice as long as the shorter leg, and the longer leg is times as long as the shorter leg
