The screencast begins by outlining the rules for finding angles in a right-angled triangle given the lengths of two of its sides. Examples are then given of applying these rules: both to finding an angle given the length of two sides in a right-angled triangle, and to finding the length of a side given the length of one of the other sides and an angle
