Draw line segment AB and divide it into 4 equal parts

Let a segment AB be given. First, let’s divide it into two equal parts. To do this, draw a circle with the same radius centered at points A and B. Draw a straight line through the intersection points of the circles. This line divides the segment AB into two equal segments. Let us denote the midpoint of the segment AB by point C. In the same way, divide each of the segments AC and BC into two equal parts. Let’s denote the midpoints of segments AC and BC by points D and E. We got four equal segments: AD, DC, CE, EB.
