How to ……
Bisect an angle.

What?
• ‘Bisect’ means to cut exactly in half.
• If you bisect an angle, you get two equal angles e.g. if you bisect a 60° angle you get two 30° angles.
• Any point on the angle bisector will be equidistant from the lines which make the original angle.

I was okay until the last bit.
Angle bisector
Equal lengths

How to bisect an angle
![Page 5: How to …… Bisect an angle.. What? ‘Bisect’ means to cut exactly in half. If you bisect an angle, you get two equal angles e.g. if you bisect a 60° angle.](https://reader036.fdocuments.in/reader036/viewer/2022082323/5697c01f1a28abf838cd1dc3/html5/thumbnails/5.jpg)
Set your compasses to a reasonable length

Place the point on the vertex of the angle
And draw 2 arcs.

Like this….

Now place the compass pointwhere one of the arcs cross
the line
And draw another arc ‘inside’ the angle
![Page 9: How to …… Bisect an angle.. What? ‘Bisect’ means to cut exactly in half. If you bisect an angle, you get two equal angles e.g. if you bisect a 60° angle.](https://reader036.fdocuments.in/reader036/viewer/2022082323/5697c01f1a28abf838cd1dc3/html5/thumbnails/9.jpg)
Should look similar to this
![Page 10: How to …… Bisect an angle.. What? ‘Bisect’ means to cut exactly in half. If you bisect an angle, you get two equal angles e.g. if you bisect a 60° angle.](https://reader036.fdocuments.in/reader036/viewer/2022082323/5697c01f1a28abf838cd1dc3/html5/thumbnails/10.jpg)
Now repeat on the other side

Draw a line from where the arcscross to the vertex of the angle

You have bisected the angle
Leave your arcs in situ
