How to determine the missing hypotenuse using special right triangles

The video tutorial covers special right triangles, focusing on the 45-45-90 triangle. It explains the properties and relationships between the legs and hypotenuse, emphasizing that the legs are equal and the hypotenuse is the leg length multiplied by sqrt 2. The tutorial provides a step-by-step calculation of the hypotenuse and concludes with a summary of the key points.

Which two types of special right triangles are introduced in the video?

• 30-30-60 and 60-60-60

• 30-60-90 and 60-60-60

• 60-60-60 and 45-45-90

• 30-60-90 and 45-45-90

In a 45-45-90 triangle, if one leg is X, what is the length of the other leg?

• X√2

• X/2

• 2X

• X

What is the relationship between the legs and the hypotenuse in a 45-45-90 triangle?

• The hypotenuse is twice the length of a leg

• The hypotenuse is half the length of a leg

• The hypotenuse is the leg length multiplied by √2

• The hypotenuse is the same as the legs

If a leg of a 45-45-90 triangle is 25, what is the length of the hypotenuse?

• 25√2

• 50√2

• 50

• 25

What is the formula used to calculate the hypotenuse in a 45-45-90 triangle?

• Leg length multiplied by 2

• Leg length divided by √2

• Leg length divided by 2

• Leg length multiplied by √2
