MGSE.9-12.G.SRT.8 Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.
MGSE.9-12.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.

Learning Targets /Success Criteria:
• I can create correct trigonometric ratios using sine, cosine and tangent.
• I can use trigonometric ratios to find missing sides in right triangles.
• I can use inverse trigonometric functions and ratios to find missing angles in a right triangle.
• I can use the Pythagorean Theorem and trigonometric ratios to solve for all side lengths of a right triangle.
