SOHCAHTOA

Front

What does SOHCAHTOA stand for?

Back

SOHCAHTOA is a mnemonic to remember the definitions of the sine, cosine, and tangent ratios in a right triangle: SOH = Sine = Opposite/Hypotenuse, CAH = Cosine = Adjacent/Hypotenuse, TOA = Tangent = Opposite/Adjacent.

Front

Which side is opposite angle x in a right triangle?

Back

The side that does not touch angle x; it is directly across from angle x.
