This right triangle trigonometry choice board includes:

  • finding a missing side
  • finding a missing angle
  • real life application problems.

Only sin, cos, and tan are used. There are no radicals. Pythagorean theorem is not used. Answer key included!

Choice board allows students to choose a certain amount of problems to complete. Great for differentiation! I left a blank for teachers to fill in how many problems they want students to complete. I offer extra credit for students who do more than the required amount.
