What Grade 10 trigonometry covers
Grade 10 trigonometry often uses right triangles to connect angles with side lengths. Students also begin seeing angle units more carefully, including degree measure and the radian measure used later.
Right triangles solve real situations
Angles of elevation and depression, ladder problems, shadows, towers, and distances can often be solved by drawing a right triangle first.
Turn the diagram into a ratio
Start with the diagram, identify the angle, label the opposite and adjacent sides, then choose the trigonometry ratio that matches the known information.
