Right Triangle Trigonometry Matching Puzzle
Using the trigonometric ratios (Sohcahtoa), students will solve right triangles for missing sides and angles. Students cut out the puzzle pieces, solve the problems, then match them, to make the solution shape. A fun, engaging way for kids to get practice with their right triangle trig! This puzzle contains 30 problems that cover Sohcahtoa, special right triangles (45-45-90 and 30-60-90), and the Pythagorean Theorem.
