Hypotenuse facts for kids
The hypotenuse is a special side in a right triangle. It's always the longest side. You can find it by looking for the side that is directly across from the 90-degree angle.
For example:
In the picture above, if angle C is the 90-degree angle, then the side labeled "c" is the hypotenuse.

Why is the Hypotenuse Important?
The hypotenuse is super important in a part of math called trigonometry. This is a branch of math that studies triangles and how their sides and angles relate. The hypotenuse helps us figure out many different mathematical calculations.
How to Find the Length of the Hypotenuse
You can find out how long the hypotenuse is if you know the lengths of the other two sides of the right triangle. You use a famous rule called Pythagoras' Theorem. This theorem helps you find the length of any side of a right triangle if you already know the other two sides.
