數(shù)學題啊,
根據(jù)下面的圖,三角形ABC.現(xiàn)在把一條邊AB延伸至D點,使得BD=AB,再延長AC至E點,使得CE=2AC.我們得到了一個更大的三角形ADE.現(xiàn)在請計算三角形ADE與ABC的面積的比率.
請翻譯As shown in the following diagram,there is a triangle ABC.Now we extend the length of Side AB to Point D,which makes
請翻譯As shown in the following diagram,there is a triangle ABC.Now we extend the length of Side AB to Point D,which makes BD=ab; while we estend the length of Side AC to point E,which makes CE=2AC;THUS we can get a bigger triangle ADE.Now please calculate the area ratio of Triangle ADE to Triangle ADE Triangle ADE to Triangle ABC.
