# Q3, W5: January 31-February 4 Geometry Teacher Kristin Andreason Geometry Honors 8 January 31- February 4 Unit 4: Right Triangles and Trigonometry
Standard(s) Taught

MAFS.912.G-SRT.3.7: Explain and use the relationship between the sine and cosine of complementary angles.

MAFS.912.G-SRT.3.8:  Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.

Learning Targets and Learning Criteria
• calculate sine and cosine ratios for acute angles in a right triangle when given two side lengths.
•  use a diagram of a right triangle to explain that for a pair of complementary angles A and B, the sine of angle A is equal to the cosine of angle B and the cosine of angle A is equal to the sine of angle B.
• draw right triangles that describe real world problems and label the sides and angles with their given measures.
• solve application problems involving right triangles, including angle of elevation and depression, navigation, and surveying.
