given ΔNOP ~QRP. enter segments in tye blanks provided that would results in a true equation

We have that triangles NOP and QRP are similar; therefore, the ratio between their correspondent sides is constant. This is
[tex]\frac{NO}{QR}=\frac{OP}{RP}=\frac{PN}{PQ}[/tex]Therefore, the answers are OP/RP or PN/PQ, any of those is correct.
