通过线段被任意折成三段能构成三角形的概率问题,推广给出了线段任意折成三段能构成锐角三角形、直角三角形和钝角三角形的概率,任意折成四段能构成四边形、平行四边形和梯形的概率,以及任意折成n段能构成n边形的概率.
We respectively compute the probabilities of a segment folded into an triangle, an acute triangle, a right triangle and an obtuse triangle, probability of on a segment folded into four sections as a quadrilateral, parallelogram and trapezoid,and probability of on a segment folded into n sections as an n polygon, which implies the probability tends to one as n tends to infinity.
