Understanding SOH CAH TOA
For any right-angled triangle, the relationships between the angles and the side lengths are defined by trigonometric functions. The mnemonic **SOH CAH TOA** helps remember these relationships:
SOH: Sine = Opposite / Hypotenuse
The sine of an angle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.
CAH: Cosine = Adjacent / Hypotenuse
The cosine of an angle is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse.
TOA: Tangent = Opposite / Adjacent
The tangent of an angle is the ratio of the length of the side opposite the angle to the length of the adjacent side.
