45 45 90 triangles
AAT 5 - Troup County
45 °-45 °-90 ° and 30 °-60 °-90 ° Right Triangles. Recall these special right triangles. Fill in the following chart using trig ratios. These are common angles, so you should have these values memorized (concentrate on sine, cosine, and tangent). θ sin θ cos θ tan θ csc θ sec θ cot θ 30° 45° 60° Look at the values that are the ...

Rules for Special Right Triangles: There are two special types of right triangles that we will be studying, the 45-45-90, and the 30-60-90. 45 – 45 – 90 30 – 60 – 90. This type of triangle is also isosceles. Rules for the 45-45-90 Right Triangle: If given one of the legs, multiply one leg by √2 to find the hypotenuse.

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.
