### Slide 2

The first thing to crack trig is to label the sides of a triangle. Right angled triangles

Simple. only for trig.

The longest side.

Remember from

Hyp Pythagoras

Adjacent

So to label the other two sides it all depends on the angle displayed.

This just means next to

the angle.…read more
