Learning Goals

Author:Katie Akesson
  • I can explain why knowing 1 acute angle in a right triangle determines the ratio of the side lengths.
  • I understand that the right triangle side length ratios have specific names: sine(Ɵ), cosine(Ɵ), tangent(Ɵ).
  • I can use technology to find the value of sine(Ɵ), cosine(Ɵ), tangent(Ɵ).
