Standards Addressed:
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 solve problems involving right triangles using the Pythagorean Theorem.
--I can use the converse of the Pythagorean Theorem to prove that a triangle is a right triangle
--I can use the Pythagorean Theorem to find missing sides of triangles.
--I can create correct trigonometric ratios using sine, cosine and tangent.
--I can use trigonometric ratios to find missing sides in right triangles.
