Please explain Pythgoras Theorem

So, Pythgoras Theorem mostly deals with right-angled triangles, ie a triangle with one 90 degree angle.

The slanted side is called the hypotenuse and let us denote it as c the bottom is called the adjacent, let's denote it a and the standing side is called opposite, let's denote it b.

Now, Pythgoras Theorem states that:

c^2 = a^2 + b^2

This theorem is often used to find the sides of triangles which can then be used to find other angles in the triangles.

And there you have it, Pythgoras Theorem!
