Its supposed to be a normal triangle and not a right triangle, the computer makes it seem like it's a right triangle but it's not.

It's Pascal's Triangle, very useful in factoring out two binomials that are being multiplied.
For example: the row with 121
(x + 1)(x + 1) =
x*x + 1x + 1x + 1*1 =
(1)x^2 + (2)x +(1)1 or x^2 +2x +1

ive done something similar called pascals triangle where each number is found by adding the two above it. The triangle is a bit different however and this might not be pascals. Its something to do with expanding brackets or factorising them i did it a year ago

I know it looks different because you cannot center it online, but I am sure it is Pascal's triangle. Just google "pascal's triangle" and that should explain it if that is what your teacher wants.

That would be Pascal's triangle. http://ptri1.tripod.com/ What it is is basically a triangle where both sides are always 1, and you just add previous numbers to form new numbers. Your triangle, however, is not correct...

Pascal's Triangle. I don't see how you would use the net to find out.
