There is a point P on the BC side of a 12cm square piece of paper ABCD, Pb = 5cm. If the paper is folded so that point a falls on point P, try to find the length of the crease
Connect PA and make NQ perpendicular to AB and point Q
BP=5,AB=12
AP=13
fold
AP is perpendicular to nm
Easy to prove triangle ABP complete
Equal to triangle nqm
MN=AP=13
That is, the length of crease is 13cm
