- the trigonometric ratios and how to use them in context.
- That we can use angles of elevation and depression to solve right-angled triangle problems.
- I can solve right-angled triangle problems involving angles of elevation and depression.
Properties of Right-Angled Triangles
“Opposite” is the opposite to the angle.
“Adjacent” is next to to the angle.
“Hypotenuse” is the long side of the right-angled triangle.
