In the diagram, StartFraction S Q Over O M EndFraction = StartFraction S R Over O N EndFraction = 4. Triangles M N O and S R Q are shown. The length of side N O is 8 and the length of side R Q is 48. The length of side O M is 15 and the length of Q S is 60. The length of side M N is 12 and the length of S R is 32. To prove that the triangles are similar by the SSS similarity theorem, which other sides or angles should be used? MN and SR MN and QR
