Construct congruent segments and angles, angle bisectors, and parallel and perpendicular lines using a straight edge and compass or a drawing program, explaining and justifying the process used.
Remarks
Example 1: Draw a triangle ABC. Duplicate it using your compass and straightedge.
Example 2: Construct the perpendicular bisector of a given line segment, justifying each step of the process.
Example 3: The city shown below has two offices (A and B) for the same newspaper. The two offices want to divide the city into two regions so that any location in one region is always closer to their own newspaper office than to the other one. Copy the map and locate the dividing line. Explain why this line meets the given criteria. Select several points in each region and make sure they are closer to their newspaper office than they are to the other one.
