# Pythagorean Challenge—Extra Credit Opportunity

Stretch your brain, master the pythagorean theorem, and earn some extra points in the process. You’ll need to show your work and be able to explain your methods for credit.

You may need some formulas…

The area of a triangle can be expressed as:

${{A}_{triangle}}=\frac{1}{2}bh$

Where b is the base and h is the height.

The area of a circle can be expressed as:

${{A}_{circle}}=\pi {{r}^{2}}$

Where r is the radius of the circle or half the diameter.

You can ask questions before school, during lunch, after school, or by sending a tweet @rudunn.

Here’s the challenge…
