Given the long leg of a special right triangle determine the missing lengths

The video tutorial explains how to identify parts of a right triangle, specifically focusing on distinguishing between the long leg and the short leg. It provides a method to calculate the short leg when given the long leg by dividing by the square root of three. Additionally, it covers how to find the hypotenuse from the short leg by multiplying by two. The tutorial concludes with advice for students to better understand these geometric concepts.

In a right triangle, how can you identify the longer leg?

• It is the side that is longer than the other leg.

• It is the side that is shorter than the hypotenuse.

• It is the side adjacent to the right angle.

• It is the side opposite the right angle.

What operation is used to find the short leg when the long leg is known?

• Multiply by 2

• Divide by the square root of 3

• Add the square root of 3

• Subtract the square root of 3

If the long leg of a triangle is 21 times the square root of 3, what is the length of the short leg?

• 42

• 21

• 21 times the square root of 3

• 42 times the square root of 3

How do you calculate the hypotenuse from the short leg in a right triangle?

• Divide by 2

• Subtract 2

• Add 2

• Multiply by 2

If the short leg of a triangle is 21, what is the length of the hypotenuse?

• 42 times the square root of 3

• 21

• 21 times the square root of 3

• 42
