## Segment Bisector Steps

Any segment, line or plane that intersects a segment at its midpoint is called a segment bisector.

**Step 1:**Use the "point" tool to create two separate points labeled A and B.**Step 2:**Use the "segment" tool to connect point A and B by selecting each point.**Step 3:**Create a point between A and B that is closer to B than A. Label the new point C.**Step 4:**Use the "compass" to connect the endpoint A to C. To do so, select point A, then point C, then point A to mark center of the circle.**Step 5:**Repeat step 4 and select points A, C, then B to mark the center of the circle. You should now have two circles where the original endpoints A and B are the center of the circle. Your circles should intersect.**Step 6:**Use the "point" tool to select the intersections between the two circles.**Step 7:**Create a "segment" connecting the intersections. You have now bisected the segment!**Step 8:**Mark the intersection of segment AB and the segment created in step 7 as M (midpoint).**Step 9:**Measure segment AM and segment MB using the "angle tool", "measure distance" by selecting points A and M and then again by selecting points M and B. The measurements should be equal.**Step 10: Write your name using the "ABC" tool. Step 11:**Take a screen shot of your work below.
