Did anyone work out how to prove the two triangles were similar?
i prooved the angles were simialr, but when it came to prooving y i mucked it up.
Proof that I used was:
As angle QLM is 180 dergrees. QLM is 90 degrees (given) + MLN+ QLK.
therefore 90 degrees is MLN + QLK
Triangle MNL is 180 degrees = 90 degrees (given) + MLN +LMN
therefore 90 degrees is MLN +LMN
therefore it follows that by combining the equasions. MLN + LMN = QLK + MLN
therefore LMN = QLK
whch gives you a second angle. the first is the 90 degrees and the third can be prooven through angle sum of triangle. Therefore you have AAA therfore the two triangles are equal!
