Using Pythagoras' Theorem, can you work out the answers to given problems? These should be quite easy if you know Pythagoras' Theorem. Have fun!

**1. What is Pythagoras' Theorem? Do not give the formula, explain what it is.****2. The length of the opposite and adjacent sides are 3cm and 4cm. What is the length of the hypotenuse?****3. If I knew what the hypotenuse and what the adjacent OR the opposite side was, what would be the formula for working out the missing side?****4. The length of the adjacent side and the opposite side is 9cm and 11cm. What is the length of the hypotenuse?****5. The length of the opposite and adjacent sides are 19cm and 17cm. What is the length of the hypotenuse?****6. The length of the hypotenuse is 36cm. The length of the opposite side is approximately 7.81cm. What is the length of the adjacent side?**
