半年前，我們舉辦了第一届夢之隊 Dream Team 计算机绘图竞赛。

這次，稚嫩的小手將從鍵盤鼠標移到紙上桌面，操控直尺和圓規。

Contest02

How well can you use straightedge and compass on paper? You have two options to demonstrate your dexterous hands.

After everyone submits his/her work, we will vote to generate the final winner.

Option One: draw more than 20 points - each has same distance to the given point and line.

Option Two: draw more than 20 points - each has constant sum of distances to the two given points.

感興趣的小朋友不妨試試這兩個挑戰。
