Right Triangles & Trigonometry
The Pythagorean theorem and its converse; classifying triangles; special right triangles; the SOH-CAH-TOA trig ratios; finding sides; and angles of elevation and depression with inverse trig.
Builds on
Similarity (Unit 7) — the trig ratios are fixed BECAUSE same-angle right triangles are similar; plus the triangle angle sum (Unit 4) and parallel-line angles (Unit 3).
