Unit Description:
​In this unit,...


Learning Goals:  We are learning to…
  • Find the measure of sides and angles in right triangles using primary trigonometry ratios (SOH CAH TOA)
  • Investigate and verify the sine law
  • Investigate and verify the cosine law
  • Describe conditions that determine when to use sine law, and when to use cosine law
  • Find the measure of sides and angles in non-right triangles using sine law and cosine law
 
Success Criteria:  I can…
  • Label the opposite, adjacent, and hypotenuse of a right triangle according to the angle of interest
  • Determine which primary trigonometry ratio to use to solve a triangle
  • Determine when it is appropriate to use inverse ratios (sin-1, cos-1, tan-1)
  • Label angles of elevation and angles of depression
  • Use sine law and cosine law to calculate sides and angles in a non-right triangle
