When I was your age, even I used to ask all sots of questions in class, sometimes I would get snubbed but then other times I learnt a lot.

** Never shy away from asking for if there were no questions we would never get the answers**

Thank you.

]]>The circumference of a circle is given by 2πr, where r is its radius.

So that means that your right-angled triangle has a base of 2πr and r.

The area of a right-angled triangle is given by 1/2 base x height.

So that means that the area is 1/2 x 2πr x r = πr², the area of a circle.

I'd never heard that theorem(?) before, but because it's a fairly easy proof, I wouldn't think that it was discovered by anyone very significant.

]]>The area of a right-angled triangle and a circle will be equal if:

i) the height of the triangle is equal to the radius of the circle

**and **

ii) the base of the triangle is equal to the circumference of the circle

I have looked on the internet but cant find anything on it.

A little explanation about it would be nice too:).. but im only 15 so it needs to be kept fairly simple.

Thanks.
