Pythagoras is a mathematical concept regarding right-angled triangles. The rule of Pythagoras' Theorem is that in a right-angled triangle, $c^2=a^2+b^2$. This, alongside trigonometry allows for a variety of applications.

## UsageEdit

Pythagoras' Theorem can be be applied to any right angled triangle. The main application of Pyrathogoras' Theorm is when a right angled triangle is given but with only two sides' length given. Every side can be solved through one of the following formulas:

• $c^2=a^2+b^2$, ∴ $c=\sqrt{a^2+b^2}$
• $a^2=c^2-b^2$, ∴ $a=\sqrt{c^2-b^2}$
• $b^2=c^2-a^2$, ∴ $b=\sqrt{c^2-a^2}$

## TheoryEdit

Pythagoras' Theorem relies on a few rules, including $c<a+b$ but the rule is basic and accurate.
