The lesson plan details a mathematics class on trigonometric ratios for Form 3H students. The teacher will introduce trigonometric ratios, explain how to identify the sides of a right triangle with respect to a given angle, and how to use sine, cosine, and tangent ratios to calculate angles and side lengths. Students are expected to already know how to identify right triangles. Teaching aids include a chart showing trigonometric ratios and a builder's square.
