If you know that one base of a right triangle is 3 units long and the other base is 4 units long, then you can use the Pythagorean theorem to find the length of the hypotenuse.

Square both the bases and add them together.

32=9

42=16

9+16=25

Then take the square root of that.

The square root of 25 is five.

So we know that the hypotenuse is 5 units long.
