Construct a Perpendicular Bisector
Directions:
Step 1. Use the Segment tool that is located in the Line tool to draw a line segment. The line segment will be segment AB.
Step 2. Use the Circle with Center through Point tool to draw a circle centered at point A with
segment AB as its radius.
Step 3. Use the Circle with Center through Point tool to draw a circle centered at point B with
segment AB as its radius.
Step 4. Using the Intersect tool to mark the points of intersection of the two circles. The
intersect tool is found by clicking the second button from the left on the
toolbar.
Step 5. Use the Line tool to draw a line through the two points of intersection. The line will be
line DC.
Step 6. Use the Intersect tool to mark the point of intersection of the line and the segment.
The point of intersection will be point E.
Step 7. Use the Angle tool to measure the angle at the point of intersection of the line and the
segment. Click point B. Then, click the point of intersection of the line and
the segment. Finally, click the topmost point of the line.
Step 8. Use the Distance or Length tool to measure the distance between the point of
intersection of the line and the segment and both endpoints of segment AB.
