Right Triangle Trigonometry Quiz

What are the three primary trigonometric functions used in right triangle calculations?

• Sine, Secant, Cosecant

• Tangent, Cotangent, Cosecant

• Sine, Cosine, Tangent

• Cosine, Cotangent, Secant

Which trigonometric ratio is defined as the opposite side over the hypotenuse?

• Tangent

• Sine

• Secant

• Cosine

If you know the hypotenuse and the adjacent side of a right triangle, which trigonometric function would you use to find the angle?

• Cosine

• Sine

• Tangent

• Cosecant

What is the first step in using trigonometric functions to find a missing side of a right triangle?

• Identify the hypotenuse

• Choose the correct trigonometric function

• Set up a proportion

• Use the Pythagorean theorem

In the equation 'cosine of angle = adjacent/hypotenuse', what is the next step after setting up the equation?

• Cross multiply

• Add the hypotenuse

• Subtract the adjacent

• Divide by the angle

When solving for a missing side using trigonometric functions, when should you use a calculator?

• Before setting up the equation

• During the cross multiplication

• After the variable is isolated

• After choosing the trigonometric function

If an angle in a right triangle is 72 degrees, which trigonometric function would you use to find the side opposite to it?

• Cosecant

• Sine

• Tangent

• Cosine

In a right triangle, if you know two sides and need to find the third, which theorem could you use?

• Law of Cosines

• Law of Sines

• Pythagorean theorem

• Triangle Sum Theorem

What is the relationship between the size of an angle and the length of the side opposite to it in a right triangle?

• Larger angle, shorter side

• Angle size does not affect side length

• Larger angle, larger side

• Smaller angle, larger side

Which trigonometric function would you use if you have the opposite side and need to find the hypotenuse?

• Secant

• Tangent

• Cosine

• Sine
