Trigonometry SOH CAH TOA

Front

What is the hypotenuse in a right triangle?

Back

The hypotenuse is the side opposite the right angle.

Front

What does SOHCAHTOA stand for?

Back

SOHCAHTOA is a mnemonic to remember the trigonometric ratios: SOH = Sine = Opposite/Hypotenuse, CAH = Cosine = Adjacent/Hypotenuse, TOA = Tangent = Opposite/Adjacent.

Front

In a right triangle, which side is adjacent to the right angle?

Back

The two sides that form the right angle are considered adjacent to it.

Front

How do you calculate the sine of an angle?

Back

Sine of an angle = Opposite side / Hypotenuse.

Front

How do you calculate the cosine of an angle?

Back

Cosine of an angle = Adjacent side / Hypotenuse.

Front

How do you calculate the tangent of an angle?

Back

Tangent of an angle = Opposite side / Adjacent side.
