What is the relationship between the sides of a 45-45-90 triangle?

• Hypotenuse is twice as long as a leg

• One leg is √2 times longer than the other

• Legs are congruent; hypotenuse is leg times 2

• Legs are congruent; hypotenuse is leg times √2

Why does the hypotenuse of a 45-45-90 triangle have a length of x√2 when the legs are of length x?

• Because of the Pythagorean theorem

• Due to the triangle's angles

• It's a property of all triangles

• Because the legs are perpendicular
