www.math.utoledo.eduusing right triangle trigonometry. Second illustration of all the six trigonometric functions. NOTE: Since the three angles of any triangle sum to 180q and the right angle in the triangle is 90q, then the other two angles in the right triangle must sum to 90q. Thus, the other two angles in the triangle must be greater than 0q and less than
