Using Special Triangles to Find Unknown Values • [2.1d] Pre-Calculus 11

Learn how to solve applied problems involving unknown angles and sides by writing trig ratios using the two 'special triangles', 45-45-90 and 30-60-90.

My instructional approach emphasizes conceptual understanding of and connections between concepts and ideas, rather than just pure memorization.

Corresponds to chapter 2, section 2.1 in McGraw-Hill's Pre-Calculus 11, but also fits with the trigonometry unit from almost any other Pre-Calculus course or textbook.
