Task goals
- Label the hypotenuse, opposite, and adjacent sides of a right-angled triangle relative to a marked angle, in any orientation.
- Choose the correct ratio (sin, cos, or tan) from the marked angle and the pair of sides involved, using SOH CAH TOA.
- Find a missing opposite, adjacent, or hypotenuse side by substituting into the chosen ratio and solving.
- Round an answer to a stated accuracy (3 significant figures or a given number of decimal places) when the result is not exact.
- Apply the ratios to real-world contexts, including angles of elevation and depression.
