Covers similar triangles and corresponding angles, finding an unknown height in a similar triangle, and tangent ratios of varying angles (hypotenuse, adjacent, and opposite sides). Explains how to use a calculator to find the tangent ratio of any angle and how to use tangent ratios to find either an unknown adjacent or opposite side length.
