Is it a right-angled triangle?
Does the question include angles?
Trigonometry
sinθ = opp/hyp
cosθ = adj/hyp
tanθ = opp/adj
Pythagoras
a^2 + b^2 = c^2
c^2 - b^2 = a^2
c^2 - a^2 = b^2
Cosine rule
a^2 = b^2 + c^2 - 2bc CosA
A = Cos^-1 ((b^2 + c^2 - a^2)/2bc)
Sine rule
SinA/a = SinB/b = SinC/c
a/SinA = b/SinB = c/SinC
Area of triangle
Area = 1/2*a*b*SinC
