What is the sine ratio?

Back

The sine ratio is defined as Sin = Opposite / Hypotenuse.

Front

What is the cosine ratio?

Back

The cosine ratio is defined as Cos = Adjacent / Hypotenuse.

Back

TOA stands for Tangent = Opposite / Adjacent.

Front

How do you calculate the sine of an angle?

Back

To calculate the sine of an angle, divide the length of the opposite side by the length of the hypotenuse.

Front

How do you calculate the cosine of an angle?

Back

To calculate the cosine of an angle, divide the length of the adjacent side by the length of the hypotenuse.

Front

How do you calculate the tangent of an angle?

Back

To calculate the tangent of an angle, divide the length of the opposite side by the length of the adjacent side.

Front

What is the relationship between sine, cosine, and tangent?

Back

Tangent can be expressed as the ratio of sine to cosine: Tan = Sin / Cos.

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.
