Math Problem Statement

How can you construct congruent segments and congruent angles using a compass and straightedge?

Solution

The image explains how to construct congruent segments and congruent angles using a compass and a straightedge. Here is a summary of the instructions:


Steps to Construct a Congruent Segment

  1. Step 1:

    • Begin with a given segment and label its endpoints AA and BB.
    • Set the compass to the radius ABAB.
  2. Step 2:

    • Draw a point CC not on the segment.
    • Sweep an arc from point CC using the compass setting from Step 1.
    • Any point on the arc can serve as the other endpoint of the congruent segment.

Steps to Construct a Congruent Angle

  1. Step 1:

    • Draw an angle TSP\angle TSP and name it.
  2. Step 2:

    • Draw a ray GH\overrightarrow{GH}. This ray will be one side of the congruent angle.
  3. Step 3:

    • Use a compass to draw an arc centered at SS that intersects both sides of TSP\angle TSP (at points TT and PP).
  4. Step 4:

    • Label the points of intersection AA and BB for further construction.

Relative Questions:

  1. How can you verify that two segments are congruent using only a compass?
  2. What is the significance of arcs in constructing congruent angles?
  3. How can you replicate an angle if no straightedge is available?
  4. What is the role of labeling intersection points in geometric construction?
  5. How can you construct perpendicular bisectors using a compass and straightedge?

Tip: When working with a compass, ensure that the radius remains consistent to avoid construction errors.
