因 線段MR//線段SQ 而未說 線段MR//線段OP,
N, S, Q 三點可能不共線.
△MNS～△MOP
∴ NS : OP = 1 : 4
即 NS = (1/4)OP
△PSQ～△PMR
∴ SQ : MR = 3 : 4
即 SQ = (3/4)MR
OP = MR
∴ NS : SQ = (1/4)OP : (3/4)MR = 1 : 3
N, S, Q 三點可能不共線.
△MNS～△MOP
∴ NS : OP = 1 : 4
即 NS = (1/4)OP
△PSQ～△PMR
∴ SQ : MR = 3 : 4
即 SQ = (3/4)MR
OP = MR
∴ NS : SQ = (1/4)OP : (3/4)MR = 1 : 3
