The Pythagorean Theorem is a really cool part of geometry that helps us understand right triangles better.

Here’s the main idea:

The formula is:

$a^2 + b^2 = c^2$

Let’s break it down:

• $a$ and $b$ are the lengths of the two sides that make the right angle.
• $c$ is the length of the hypotenuse. This is the longest side and is opposite the right angle.

If you need to find the length of one side, you can easily rearrange this formula to solve for it.

Key Parts:

1. Legs ($a$, $b$): These are the two shorter sides that create the right angle.
2. Hypotenuse ($c$): This is the longest side of the triangle.

The Pythagorean Theorem is really helpful! It can be used to find distances and is a key building block for many math concepts and real-life situations.

Just remember, it only works for right triangles!
