Students learn to find the missing side lengths and the missing angle measures in right triangles using sine, cosine, and tangent. Note that a scientific or graphing calculator is required for the problems in this lesson.

To access the complete lesson on this topic, go to www.yourteacher.com. Students learn that the sine of an angle of a right triangle is equal to the length of the side opposite the angle over the length of the hypotenuse (SOH), the cosine of an angle of a right triangle is equal to the length of the side adjacent to the angle over the length of the hypotenuse (CAH), and the tangent of an angle of a right triangle is equal to the length of the side opposite the angle over the length of the side adjacent to the angle (TOA). Students are then asked to find the values of the sine, cosine, and tangent of given angles in given right triangles.
