網上有很多這樣的畫。

在我六歲的時候，我就聽說了「簡筆畫」，但是我不知道去哪裏學。

不給一個數字，求角度

2024-06-302024-06-27 by ejsoon

上圖中，AB = AC = CD = DE，並且 BE = BD，求 ∠EBD 的角度。（來自研發養成所）

雖然4rdp只給此題打了兩顆星，但是它卻把我難倒了，連續多日求解無果。

【聽歌】千嬅盛放

感謝楊千嬅在她年輕的時候，這麼努力工作，為我留下這麼多好聽的歌。楊千嬅真的是我喜歡的類型，長相甜美，性格直率。聽她的歌，就像有一個朋友在陪你旅行。感謝《千嬅盛放》的策劃及製作人，讓我這個遲到的「歌迷」不必費力收集。雖然人已不可能回到2009年之前，但是歌可以。

ABCD構成了一個正方形，其餘條件如圖所示，求藍色區域三角形的面積。

如果我告訴你答案是

解決辦法是不依賴別人。當一個人徹底擺脫了對別人的依賴，甚麼都要靠自己時，他可能就學會自勤自勉了。

请问，如果我懒，该怎么解决？

感謝Bridan提出寶貴意見！「把 hat 0, hat 1, turtle 0, turtle 1 換成圖案標示，使用上會更直覺」我也是這樣想的，會在未來加上。「當已點選某圖塊後，按新增其它圖塊，應保留原先被選的圖塊，並新增另外的拚塊。」你的意思應該是當一個圖塊處於吸附狀態時（邊緣變綠），新增圖塊應使前圖塊掉落（而非消失）。這個我也會在後面改進。
