Draw an angle bisector: The steps are as follows: Draw an angle first, 1. Make an arc with O as the center and appropriate length as the radius, and pass through OA at m and OBN at .2. Centered on m and n respectively. More than that.

1/2

The length of MN is an arc with radius. These two arcs intersect at C.3 in ∠AOB. Ray OC is demand.

Draw perpendicular bisector: The steps are as follows: First, take the length of a line segment greater than 1/2 with compasses, and draw arcs on the upper and lower interfaces on both sides of the line segment to connect the two focuses.

The drawing method of the golden section point: the steps are as follows: 1. Make right angle AOB=90 degrees, make AO= 1 unit length, and BO=2 units length.

2. connect AB.

3. Intercept AC= 1 unit length on AB.

Then BC line is the root number 5 minus 1, that is, point C is the golden section of AB.

Thank you. I hope this helps you. ...
