Re: [algogeeks] Re: intel puzzle
@priyaranjan No,Your triangle will be right angle triangle. In fact any triangle chosen will be right angle triangle. Proof: suppose there are 2 planes kept at parallel with each other.(top bottom) join corresponding vertices of up to down and form cube. Now 3 points chosen can be on same plane .(means 2 must be adjacent) so right angle triangle is only possible or at least 2 points are on same plane and 3rd point is other plane(pigeon hole as only 2 holes are there for 3 pegions) Now as 3 rd point always lies on perpendicular point so triagle formed will always be right angled.
