Another Alleyn maths question
24d...find the area of the square....
http://www.alleyns.org.uk/alleyn/docume ... _paper.pdf" onclick="window.open(this.href);return false;
The only way I can do it is using the pythagoras theorem. Is there another way, more fitting KS3.
Please help to make it simple....
Thanks

Re: Another Alleyn maths question
Draw a line from each vertex ie from (3,1) draw a line horizontal to the left, from (0,3) draw it vertically down etc.
if you repeat you should see four triangles [each half of a rectangle 3 squares by 2 squares] and a small square in the middle.

Thanks Guest55. That's great.
I'm convinced questions like this are either for Maths professionals or a quite clever 10 year olds.... nothing in between.

Each line goes along 3 and up/down 2. As soon as it is drawn it is easy to see.
