Geometry Week 5
January 30th – Feb 3rd 2017
TEKS:
G.9A determine the lengths of sides and measures of angles in a right triangle by applying the trigonometric ratios sine,
cosine, and tangent to solve problems
G.9B apply the relationships in special right triangles 30-60- 90 and 45-45-90 and the Pythagorean theorem, including
Pythagorean triples, to solve problems
G.8B identify and apply the relationships that exist when an altitude is drawn to the hypotenuse of a right triangle,
including the geometric mean, to solve problems
Academic Vocabulary:
