  "abstract": "By analyzing an $e^+e^-$ collision data sample with an integrated luminosity of 20.3 fb$^{-1}$ collected with the BESIII detector at the center-of-mass energy of 3.773 GeV, we perform the first amplitude analysis on the doubly Cabibbo-suppressed decay $D^+ \\to K^+π^+π^-π^0$ and report the first observation of $D^+ \\to K^{*0}ρ^+$ and $D^+\\to K^{*+}ρ^0$. The corresponding branching fractions are $(5.67\\pm0.41_{\\rm stat}\\pm0.17_{\\rm syst})\\times10^{-4}$ and $(5.32\\pm0.57_{\\rm stat}\\pm0.24_{\\rm syst})\\times10^{-4}$, respectively. These two $D\\to VV$ decay both have large transverse polarizations. The longitudinal polarization fractions are measured to be $0.111\\pm0.024_{\\rm stat}\\pm0.008_{\\rm syst}$ and $0.263\\pm0.049_{\\rm stat}\\pm0.015_{\\rm syst}$, respectively. The branching fraction of the decay $D^+\\to K^+ω$ is measured to be $(4.76\\pm0.84_{\\rm stat}\\pm0.13_{\\rm syst})\\times 10^{-5}$.",
