Area Of A Triangle 1/2absinC
The area of a triangle is ½ the base X perpendicular height. If we don’t have the perpendicular height, there is another formula we can use: 1/2absinC which we look at in this video. We need two sides and the angle in between. This will...

Sine Or Cosine Rule?
Not every triangle is a right-angle triangle, so we can't always use Pythagoras and SOHCAHTOA to find missing sides and missing angles. We instead use the sine rule or the cosine rule. They can both be used to find either missing sides...
