This PowerPoint contains a lesson on using inverse trig functions to calculate angles in a right angled triangle. The starter recaps finding a side length using standard trig functions. Then explains that rearranging SohCahToa triangles results in finding the sin, cos, tan of an angle and that there is one more step. Supporting questions are at the end with a GCSE style question, which is no more challenging than the other questions.
