大家好，今天我想向大家介绍数学史一个的著名问题：三等分一个角。请看这个图，ABCD是长方形，F是DA延长线上的一点，G是CF上一点，并且角ACG=角AGC，角GAF=角GFA。下面，由我来证明给大家看：因为ABCD是长方形，所以DF//BC,角FCB=角CFD，又因为角GAF=角GFA，所以AC=AG，AG=GF，所以AC=GF,角AGC=角GAF+角GFA=角AGC，所以角ECB=三分之一角ACB。
下面，我还想为大家唱首歌，名叫right here waiting,希望大家喜欢

Hello, every one! Today, I want to introduce a popular question in the history of mathematics. An angle into three equal. Look at this picture, ABCD is a rectangle，F is a point on the Extension Line of DA and G is a point on the Extension Line of CF. What's more, the angle AGC equals the angle ACG, and angle GAF equals angle GFA. All right, let me prove it to you. First, ABCD is a rectangle, so DF is parallel with BC, and the angle FCB equals the angle CFD. Then, because the angle GAF equals the angle GFA, AC equals AG equals GF, and the angle AGC equals the sum of the angle GAF and GFA, which equals to the angle AGC. Finally the angle ECB equals one third of the angle ACB.
That's all, thanks. Oh, I'm so happy now and I want to sing a song to you. It's right here waiting. I hope you like it.
