Understanding Trigonometric Ratios

What is the sine ratio in a right triangle?

• sin(θ) = opposite / hypotenuse

• sin(θ) = hypotenuse / opposite

• sin(θ) = adjacent / hypotenuse

• sin(θ) = opposite / adjacent

Which ratio represents cosine in a right triangle?

• Adjacent side / Hypotenuse

• Opposite side / Hypotenuse

• Adjacent side / Opposite side

• Hypotenuse / Opposite side

What is the tangent ratio defined as?

• Tangent ratio = adjacent/opposite

• Tangent ratio = opposite^2/adjacent

• Tangent ratio = adjacent^2/opposite

• Tangent ratio = opposite/adjacent

In a right triangle, what does the cosecant ratio represent?

• The cosecant ratio represents the opposite side divided by the adjacent side.

• The cosecant ratio represents the adjacent side divided by the hypotenuse.

• The cosecant ratio represents the hypotenuse divided by the adjacent side.

• The cosecant ratio represents the hypotenuse divided by the opposite side.

Which of the following is the correct definition of secant?

• A line that touches a curve at one point.

• A line that runs parallel to a curve.

• A line that connects two points on a straight path.

• A line that intersects a curve at two or more points.
