**Introduction:**

So many things we use in maths don't seem relevant
in our "real" lives. Do you ever wonder why it will be faster to travel
"as the crow flies" instead of walking the original paths? About
how tall a ladder should be so that the fireman can save the child from the
burning building? All these questions can be solved by using the Pythagorean
Theorem. It's really as simple as a.... b..... c....

## Questions

**Question
1...**

## Pythagoras did lots of amazing things, but where did
this man come from?

What was his big contribution to mathematics?

And what is this theorem used for?

**
Question 2...**

**What is the Pythagorean Theorem?**

Explain what the relationship is between the
sides of a right triangle.

** Question 3...**

**CHOICE 1**

**CHOICE 2**

**
CHOICE 3**

**Question
4...**

**How can this be used in "real life?"**

See problems that use the Pythagorean
Theorem, both from a text and using the samples

in
context.
