How to bisect an angel by folding Paper

如何通过折纸来平分角？

请记住下面的英文说法。

Divided this angle in half

Make seventy degree protractor

draw a line joining the Corner With this point。

fold your paddy paper so that it forms an x

i'm going to trace that

I'm going to name This angle using three points. i call it pqr

TO Create the angel bIsector

i need to fold the paddy paper so that ray qp overlaps ray qr

The crease goes to through vertex Q

The rays are overlapping each other Here .

the vertex is along the crease.

Open my paper up。

Name the line m

M Is the angle by sector of angle pqr

Indicate that using arc and tick marks

请将下面的中文翻译成英文。

把这个角分一半儿

用量角器做一个70度的角。

画一条线，这条线是连接角和这个点的。

折抵你的白纸让他形成一个x.

我将要画他。

我要命名这个角用三个点。 我叫他PQR

为了创建平分角，

我需要折叠纸，让射线qp重叠在射线qr上面。

折痕将通过顶点Q

所以两条射线相互重叠在这里。

顶点就在折痕处。

打开我的白纸。

这条线就叫

就是角pqr的平分线。

用圆弧和对勾来做标记。
