What is the side across from the right angle in a right triangle called?

• Hypotenuse

• Adjacent

• Opposite

• Base

What is the formula for sine in terms of a right triangle?

• Sine = Adjacent side / Hypotenuse (sin = a/r)

• Sine = Opposite side / Hypotenuse (sin = p/r)

• Sine = Opposite side / Adjacent side (sin = p/a)

• Sine = Hypotenuse / Opposite side (sin = r/p)

If the opposite side is 21 and the adjacent side is 28, what is tan Z?

• 21/28

• 28/21

• 21

• 28

Which trigonometric function is used when you have the opposite side and hypotenuse?

• Cosine

• Tangent

• Sine

• Secant

How do you find sin C if the opposite side is 28 and the hypotenuse is 35?

• sin C = 28/35

• sin C = 28/21

• sin C = 35/28

• sin C = 35/21

What is the value of cos 60°?

• 1/2

• √3/2

• 0

• 1

How do you calculate the hypotenuse if you know the lengths of the other two sides?

• Use the Pythagorean theorem: c = √(a² + b²)

• Add the lengths of the two sides: c = a + b

• Multiply the lengths of the two sides: c = a * b

• Use the formula for the area of a triangle: A = 1/2 * a * b

What is the relationship between the sides of a 30-60-90 triangle?

• 1:1:1

• 1:√2:2

• 1:√3:2

• 1:2:√3

What is the Pythagorean theorem?

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

• In any triangle, the sum of the angles equals 180 degrees.

• The area of a circle is πr².

• The square of the hypotenuse is equal to the sum of the squares of the other two sides.

What is the formula for tangent in terms of a right triangle?

• Tangent = Opposite side / Adjacent side (tan = o/a)

• Tangent = Adjacent side / Hypotenuse (tan = a/h)

• Tangent = Opposite side / Hypotenuse (tan = o/h)

• Tangent = Hypotenuse / Adjacent side (tan = h/a)
