Trig Ratios

In a right triangle, what does the 'Hypotenuse' refer to?

• The shortest side of a right triangle, adjacent to the right angle.

• The longest side of a right triangle, opposite the right angle.

• The side opposite the smallest angle in the triangle.

• The side that forms the right angle with another side.

What is the formula for Tangent?

• Tangent = Opposite / Adjacent

• Tangent = Adjacent / Opposite

• Tangent = Opposite + Adjacent

• Tangent = Opposite - Adjacent

What is the formula for Cosine?

• Cosine = Opposite / Hypotenuse

• Cosine = Adjacent / Hypotenuse

• Cosine = Hypotenuse / Opposite

• Cosine = Adjacent + Hypotenuse

How do you find the sine of an angle in a right triangle?

• By dividing the length of the side opposite the angle by the length of the hypotenuse.

• By adding the lengths of the two shorter sides.

• By multiplying the length of the hypotenuse by the cosine of the angle.

• By finding the square root of the hypotenuse.

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

• Tangent = Sine / Cosine.

• Tangent = Cosine / Sine.

• Tangent = Sine + Cosine.

• Tangent = Sine - Cosine.

How do you find the tangent of an angle in a right triangle?

• By dividing the length of the side opposite the angle by the length of the side adjacent to the angle.

• By adding the lengths of the opposite and adjacent sides.

• By multiplying the lengths of the opposite and adjacent sides.

• By subtracting the length of the adjacent side from the opposite side.

What is the formula for Sine?

• Sine = Opposite / Hypotenuse

• Sine = Adjacent / Hypotenuse

• Sine = Opposite / Adjacent

• Sine = Hypotenuse / Opposite

What are the three primary trigonometric ratios?

• Sine (sin), Cosine (cos), and Tangent (tan)

• Sine (sin), Secant (sec), and Cosecant (csc)

• Cosine (cos), Cotangent (cot), and Secant (sec)

• Tangent (tan), Cosecant (csc), and Cotangent (cot)

What does 'Opposite' mean in the context of a right triangle?

• The side adjacent to the angle of interest.

• The side opposite the angle of interest.

• The longest side of the triangle.

• The side that forms the right angle.

How do you find the cosine of an angle in a right triangle?

• By dividing the length of the side opposite to the angle by the length of the hypotenuse.

• By dividing the length of the side adjacent to the angle by the length of the hypotenuse.

• By adding the lengths of the two legs of the triangle.

• By multiplying the length of the hypotenuse by the sine of the angle.
