Let $ABCD$ be an isosceles trapezium so that $AD\parallel BC$ and $AB=CD$. Let $\omega$ be the incircle of $\triangle BCD$ and $\Gamma$ be any circles that touches $\overline{AB}$ and $\overline{AC}$ and intersects $BC$ at $U$ and $V$. Let $DU$ and $DV$ meet $\omega$ at $J$ and $K$ respectively. Prove that $JK\parallel BC$.
