1. Calculate the sine, cosine, and tangent to angle G and the corresponding angles of your similar triangles using your calculator or using Sketchpad’s calculator. Be sure the grader can see and identify your calculations. Using Sketchpad and transformations, create two triangles similar to the one below.

In the lesson launch, students examine similar right triangles and are introduced to the vocabulary that describes the ratio of two sides of a triangle: sine, cosine, and tangent. Student understanding of vocabulary related to right triangles (adjacent side, opposite side, hypotenuse) that has been previously introduced is reinforced.

Lesson summary: The students will explore the similar right triangles and geometric mean relationships created when the altitude from the right angle to the hypotenuse of a right triangle is drawn. First the students determine what angles of the three triangles (the original right triangle, and the two on each side of the altitude) are congruent.

Indirect Prerequisites: Scale factors, similar triangles, right-angled triangles. Definition: The Tangent scale factor (TSF) is what you multiply to get from the Adjacent to the Opposite sides of a triangle. This fits in with the scale-factor theme around this point in the scheme – percentages, direct proportion.
