Students use the Pythagorean Theorem to ﬁnd missing side lengths and apply properties of 30°-60°-90° and 45°-45°-90° triangles. The sine, cosine, and tangent trigonometric ratios are developed as applications of right triangle geometry. Students use the ratios to ﬁnd unknown lengths and angle measures in diagrams and real-world scenarios involving angles of elevation, angles of depression, and vectors.
- You will learn the Pythagorean Theorem and its converse
- You will use the Pythagorean Theorem to find relationships in special right triangles.
- You will use similar right triangles to define the sine, cosine, and tangent ratios.
- With these ratios, you will solve height and distance problems using angles of elevation and angles of depression.
