SOH CAH TOA is a mnemonic device used in trigonometry to remember the definitions of sine, cosine, and tangent ratios for right triangles. Sine is the ratio of the opposite side to the hypotenuse, cosine is the ratio of the adjacent side to the hypotenuse, and tangent is the ratio of the opposite side to the adjacent side. These trigonometric ratios can be used to find any unknown values, such as side lengths, in a right triangle.

2. What is SOH, CAH TOA?
SOH, CAH, TOA is a branch of mathematics
that is used on particularly right triangles.

4. SOH
S- SIN
O- OPPOSITE
H- HYPOTONUSE
 The ratio of height over hypotenuse.

5. CAH
 The ratio of base to the hypotenuse.
C- Cosine
A- Adjacent
H- Hypotenuse

6. TOA
 The ratio of the length of the side
opposite the angle to the length of the
side adjacent to it.
T- Tangent
O- Opposite
A- Adjacent

7. Sine, Cosine, and Tangent can be used to
find any unknowns in a ninety degree
angle.
