Summative Assessment: Right Triangles and Trigonometry

Front

What is the sine ratio in a right triangle?

Back

The sine ratio is defined as the ratio of the length of the opposite side to the length of the hypotenuse.

Front

What is the cosine ratio in a right triangle?

Back

The cosine ratio is defined as the ratio of the length of the adjacent side to the length of the hypotenuse.

Front

What is the tangent ratio in a right triangle?

Back

The tangent ratio is defined as the ratio of the length of the opposite side to the length of the adjacent side.

Front

What is the cotangent ratio in a right triangle?

Back

The cotangent ratio is defined as the ratio of the length of the adjacent side to the length of the opposite side.

Front

What is the secant ratio in a right triangle?

Back

The secant ratio is defined as the ratio of the length of the hypotenuse to the length of the adjacent side.

Front

What is the cosecant ratio in a right triangle?

Back

The cosecant ratio is defined as the ratio of the length of the hypotenuse to the length of the opposite side.

Front

If sin(40) = w/28, what is the value of w?

Back

w = 28 * sin(40).

Front

If tan(36) = x/51, how do you solve for x?

Back

x = 51 * tan(36).

Front

What is the relationship between sine and cosine in a right triangle?

Back

sin(θ) = cos(90° - θ).

Front

What is the Pythagorean theorem?

Back

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