Quick Special Right Triangles Review

The video tutorial covers special right triangles, focusing on 45-45-90 and 30-60-90 triangles. It explains their properties, such as equal legs in the 45-45-90 triangle and the relationships between the sides in the 30-60-90 triangle. The tutorial also provides examples to demonstrate how to solve for missing sides using these properties, emphasizing the efficiency of recognizing these triangles in problem-solving.

What is a key advantage of using special right triangles over Pythagorean triples?

• They allow solving for missing sides with less information.

• They are only applicable to isosceles triangles.

• They require more information to solve.

• They are only used for equilateral triangles.

In a 45-45-90 triangle, if one leg is of length 'x', what is the length of the hypotenuse?

• 2x

• x / sqrt(2)

• x * sqrt(2)

• x

How do you find the length of a leg in a 45-45-90 triangle if the hypotenuse is given?

• Divide the hypotenuse by 2

• Multiply the hypotenuse by sqrt(2)

• Divide the hypotenuse by sqrt(2)

• Multiply the hypotenuse by 2

In a 30-60-90 triangle, what is the relationship between the short leg and the hypotenuse?

• The hypotenuse is the same as the short leg.

• The hypotenuse is twice the short leg.

• The hypotenuse is half the short leg.

• The hypotenuse is three times the short leg.

What operation is used to find the long leg from the short leg in a 30-60-90 triangle?

• Divide by sqrt(3)

• Multiply by sqrt(3)

• Divide by 2

• Multiply by 2

If the hypotenuse of a 30-60-90 triangle is 10, what is the length of the short leg?

• 10

• 10 * sqrt(3)

• 5

• 5 * sqrt(3)

In a 30-60-90 triangle, if the long leg is 5 * sqrt(3), what is the length of the short leg?

• 10 * sqrt(3)

• 5 * sqrt(3)

• 10

• 5
