Front

What is a 45-45-90 triangle?

Back

A 45-45-90 triangle is an isosceles right triangle where the angles are 45 degrees, 45 degrees, and 90 degrees.

Front

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

Back

In a 45-45-90 triangle, the lengths of the legs are equal, and the hypotenuse is √2 times the length of each leg.

Front

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

Back

The length of the hypotenuse is a√2.

Front

What is the value of the legs if the hypotenuse is 8√2?

Back

The length of each leg is 8.

Front

How do you find the length of a leg if the hypotenuse is known?

Back

Divide the length of the hypotenuse by √2.

Front

If one leg of a 45-45-90 triangle is 5, what is the length of the hypotenuse?

Back

The hypotenuse is 5√2.

Front

What is the formula to calculate the area of a 45-45-90 triangle?

Back

Area = (1/2) * leg * leg = (1/2) * a * a.

Front

If the legs of a 45-45-90 triangle are 3, what is the hypotenuse?

Back

The hypotenuse is 3√2.

Front

What is the perimeter of a 45-45-90 triangle with legs of length 4?

Back

Perimeter = 4 + 4 + 4√2.

Front

What is the length of the legs if the hypotenuse is 6√2?

Back

Each leg is 6.
