Erik is bisecting a segment with technology. Which of the following describes his next step? Draw a circle with a center C and a

lana [24]

Answer:

Trace a line between the intersection of the two circles.

Step-by-step explanation:

This is a very important technique, the next thing you do is trace a line in between the intersection of the circles and that would intercept your circle. I will show you in a drawing.
