1 Unit 3.4 Understanding Trigonometry and Solving Real-World Problems
Instructional Days: 13

2 Math Content Standards
G-SRT Similarity, Right Triangles, and Trigonometry Define trigonometric ratios and solve problems involving right triangles G-SRT.6 Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles. G-SRT.7 Explain and use the relationship between the sine and cosine of complementary angles. G-SRT.8 Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.★ Math Content Standards

3 Standards of Math Practice
SMP 2 Reason abstractly and quantitatively. Create diagram from a word problem Understand context of a real world situation SMP 4 Model with mathematics. Apply trigonometric ratios to solve problems in everyday life using pictures, manipulatives, and other technologies. SMP 7 Look for and make use of structure. Understand the connection between trigonometry and Pythagorean Theorem Understand the connection between sine and cosine of complementary angles Standards of Math Practice
