Enter what you know below

<--- Side 1
<--- Side 2
<--- Hypotenuse
     

Given a right triangle with:

Side length = 4 and Hypotenuse = 5

Calculate the remaining side:

Pythagorean Theorem Formula

Side12 + Side22 = Hypotenuse2

Solve for Side 2

Take the square root of both sides

Side 1 = √Hypotenuse2 - Side 22

Plug in Hypotenuse = 5 and Side 2 = 4

Side 1 = √52 - 42

Side 1 = √25 - 16

Side 1 = √9

Final Answer


Side 1 = 3
