 Constructions A construction is a way to draw angles or lines when you are unable to trace them. When composing a construction, you must use a compass, pencil, and straight edge. People use constructions to copy lines, construct angles, construct perpendicular bisectors, bisect angles, and even make right angles. Constructions are great and effective when a compass isn't available. My favorite construction is a perpendicular bisector. A perpendicular bisector is when you draw a line directly through the middle of a segment. When drawing a perpendicular bisector, you compose two equal segments on one segment.I enjoy finding the perpendicular bisector of a segment because it is easy and fun to draw. It reminds me of when I was a young kid. On Halloween, or other situations where this occurred, I would always to try to find the middle of a treat to share with my friend. I would never really be able to cut this treat in half so we could each have exactly half. This would be useful for me now. Step 1: Get a compass, writing utensil(preferably a pencil), and a straight edge. Step 2: You need a line segment to bisect. Draw a line segment and label it AB. Step 3: Put the tip of the compass on endpoint A. Step 4: Open your compass to more than half way of the line segment. Step 5: Draw an arc through line segment AB(make sure to go more than half way!) Step 6: Place the same compass setting on endpoint B. Step 7: Draw an arc through line segment AB. Step 8: Label the points where the two arcs intersect as Y and Z. Step 9: Place your straight edge where these two arcs intersect. Step 10: Draw a line through these arcs. Step 11: You have successfully constructed a perpendicular bisector. Celebrate!
