Common Core Math - HS Geometry
Lesson Plan
Solve right triangles
Goals / Objectives
Define what it means to "solve" a right triangle (find all unknown sides and angles)
Use trigonometric ratios to find unknown sides in right triangles
Use inverse trigonometric functions to find unknown angles in right triangles
Use the Pythagorean Theorem in combination with trigonometric ratios
Solve real-world applied problems involving right triangles (angles of elevation/depression, navigation, indirect measurement)
Choose appropriate tools (trig ratios vs. Pythagorean Theorem) based on given information
