15 cards from this deck
Tools to find angles in right triangles from two sides
Longest side opposite the right angle
Side touching the angle (not hypotenuse)
Side not touching the angle being calculated
Hypotenuse
sinx°=oppositehypotenuse\sin x° = \frac{\text{opposite}}{\text{hypotenuse}}sinx°=hypotenuseopposite
cosx°=adjacenthypotenuse\cos x° = \frac{\text{adjacent}}{\text{hypotenuse}}cosx°=hypotenuseadjacent
tanx°=oppositeadjacent\tan x° = \frac{\text{opposite}}{\text{adjacent}}tanx°=adjacentopposite
Mnemonic for remembering trig ratios
Sine = Opposite ÷ Hypotenuse
Cosine = Adjacent ÷ Hypotenuse
Tangent = Opposite ÷ Adjacent
Right-angled triangles only
sin−1\sin^{-1}sin−1, cos−1\cos^{-1}cos−1, tan−1\tan^{-1}tan−1
