初中数学八年级上册试题库(555题)
如图,\(\Delta ABC\)的外角的平分线\(BD\)与\(CE\)相交于点\(P\),若点\(P\)到\(AC\)的距离为5,则点\(P\)到\(AB\)的距离为 ___。

知识点:第十二章 全等三角形
参考答案:如图,过点\(P\)作\(PF \bot AC\)于\(F\),\(PG \bot BC\)于\(G\),\(PH \bot AB\)于\(H\),\(\because \angle ABC\)的外角平分线\(BD\)与\(\angle ACB\)的外角平分线\(CE\)相交于点\(P\),\(\therefore PF = PG = 5\),\(PG = PH\),\(\therefore PF = PG = PH = 5\)。故答案为:5。
