I am a square triangle!

[ZenGum]

I was too lazy to write the triangle out perfectly, I figured you'd get it.

It is triangular in the sense that each line has one more number than the line before, i.e they have 1, 2, 3, 4, 5, 6, 7, 8, 9 etc numbers on each line progressively.

You'll notice that the change in the angle of the side of the triangle occurs where it changes from one digit to two digit numbers. The two digit angle will continue until we get to three digits, where it will change and become flatter again.

So we could re-write the triangle leaving extra spaces between the single digit numbers:

...............1
.............2...3
...........4...5...6
..........7..8 ...9.10
.......11 12 13 14 15
.....16 17 18 19 20 21
....22 23 24 25 26 27 28
..29 30 31 32 .33 34 35 36
