$解：?(1)①?如圖：? A_0(4?，?5)?，? B_0(5?，?2) ?，?C_0(1?，?3).?$
$?(2)①?如圖：? A_1(6?，?5) ?，?B_1(7?，?2)?，? C_1(3?，?3).?$
$?②?把三角形?△A_0B_0C_0 ?向右平移?2?個(gè)單位長(zhǎng)度，得到?△A_1B_1C_1?$
$?(3) ?問(wèn)題：若直線經(jīng)過(guò)點(diǎn)? (n ?，? 0)(n\gt 0) ?，并且與?y?軸平行，你能寫(xiě)出平面直角$
$坐標(biāo)系中任意一點(diǎn)?P(a ?，? b) ?關(guān)于直線?l?的對(duì)稱(chēng)點(diǎn)的坐標(biāo)嗎???$
$對(duì)稱(chēng)點(diǎn)坐標(biāo)為?(2n-a?，?b)?$
