Students will then review the Pythagorean Theorem, formulate and test its converse, investigate Pythagorean triples, 45-45-90 and 30-60-90 special right triangles. Finally students will generalize formulas to solve right triangles and their real-world applications by correct selection and use of the tangent, sine and cosine ratios.
