Can someone explain to me the special triangles in trigonometry?

So there is a thing called special triangles.

I might have taken it at GCSE, but not really remember them. Can someone explain it to me?

There is no such thing as "special triangles"

Is there anything else you can tell us about this concept?

Are you looking at 30/60 and 45 degrees

Are you thinking of the "special angles"?

I think you mean typical angles.

Perhaps you mean the ambiguous case (when you're doing the sin rule?) :smile:

Yeah I got it thanks guys

A square split diagonally

45, 45 and 90

An equilateral triangle = equal angles

60,60,60

Equilateral triangle split in half leaves it to be 60,30,90
