Published on 05/25/2009

Activity Overview

Students will be introduced to right triangle trigonometry. They will use the TI-89 and Geometer's Sketchpad to construct a right triangle and calculate sin, cosine, and tangent of various acute angles. (Topic - Right Triangle Trigonometry)

Before the Activity

Students will be introduced to right triangle trigonometry. They will use the TI-89 and Geometer's Sketchpad to construct a right triangle and calculate sin, cosine, and tangent of various acute angles. (Topic - Right Triangle Trigonometry)

During the Activity

Students will use the TI-89 and Geometer's Sketchpad to construct and analyze the trigonometry of right triangles. This activity can be teacher directed or discovery.

After the Activity

Review student answers:

  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
