Applications of Right-Angled Triangles (VCE SSCE General Mathematics): Flashcards

Draw diagrams, identify sides/angles, select trig function

Side across from the angle

Side next to angle (not hypotenuse)

Longest side, opposite right angle

$\frac{\text{opposite}}{\text{adjacent}}$

$\frac{\text{opposite}}{\text{hypotenuse}}$

$\frac{\text{adjacent}}{\text{hypotenuse}}$

To find side when you know one angle and one side

To find angle when you know two side lengths

Calculate whole expression in one step, not separate parts
