Sine, Cosine, or Tangent?

Front

What is the definition of Sine in a right triangle?

Back

Sine is the ratio of the length of the opposite side to the length of the hypotenuse (O/H).

Front

What is the definition of Cosine in a right triangle?

Back

Cosine is the ratio of the length of the adjacent side to the length of the hypotenuse (A/H).

Front

What is the definition of Tangent in a right triangle?

Back

Tangent is the ratio of the length of the opposite side to the length of the adjacent side (O/A).

Front

What is the Pythagorean Theorem?

Back

In a right triangle, the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a^2 + b^2 = c^2).

Front

How do you find the sine of an angle?

Back

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

Front

How do you find the cosine of an angle?

Back

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

Front

How do you find the tangent of an angle?

Back

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

Front

What is the cosine of a 60-degree angle?

Back

The cosine of a 60-degree angle is 1/2.

Front

What is the tangent of a 45-degree angle?
