10 cards from this deck
sinθ\sin \thetasinθ, cosθ\cos \thetacosθ, tanθ\tan \thetatanθ
Longest side, opposite the right angle
Side opposite to angle θ\thetaθ
Side next to θ\thetaθ, not hypotenuse
sinθ=oh\sin \theta = \frac{o}{h}sinθ=ho
cosθ=ah\cos \theta = \frac{a}{h}cosθ=ha
tanθ=oa\tan \theta = \frac{o}{a}tanθ=ao
Sine=Opp/Hyp, Cosine=Adj/Hyp, Tangent=Opp/Adj
Remain constant regardless of triangle size
h2=a2+o2h^2 = a^2 + o^2h2=a2+o2
