What is the formula to find the legs of a 45-45-90 triangle?

leg = hypotenuse + √2

leg = hypotenuse - √2

leg = hypotenuse * √2

What is the formula to find the hypotenuse of a 30-60-90 triangle?

Hypotenuse = longer leg - shorter leg

Hypotenuse = shorter leg / 2

Hypotenuse = 2 * shorter leg

Hypotenuse = shorter leg + longer leg

What is the formula to find the short leg of a 30-60-90 triangle?

Short leg = (Hypotenuse) - (1/2)

Short leg = (Hypotenuse) + (1/2)

Short leg = (Hypotenuse) * (2)

Short leg = (Hypotenuse) * (1/2)
