I might have gone around the world to get this answer but here goes

I let

AP=AS=QC=CR=t

and

PB=BQ=RD=DS=g

I then used algebra to get an expression for the area of the triangles and put it equal to 200

from this I could get t in terms of g

Then you can use pythagoras to find QR squared and QP squared in terms of g

Then you can use pythagoras again to find PR. - Nov 26th 2013, 10:08 AMWilmerRe: iscoceles triangle help
I think VegasGunner is getting his homework done...

I wouldn't give him/her a full solution: that's not really helping... - Nov 26th 2013, 10:15 AMjohngRe: iscoceles triangle help
Hi,

It "looks" like PQRS is a rectangle, but this should be verified. The attachment shows a solution:

Wilmer, you may be right. I have so much fun drawing pictures that I didn't think about this being homework. I'll restrain myself in future. - Nov 26th 2013, 01:11 PMWilmerRe: iscoceles triangle help

Hi Johng

How do you draw pictures like that.

I only discovered Latex this month. I have lots of stuff to learn. And, it is all fun.
