The locus of all points that are the same distance from A as from B.
Step-by-step explanation:
Let's observe the steps as,
1. Connect A and B and draw a line segment AB.
2. Construct an arc above and below the line segment AB by taking A as the center and radius greater than AB/2.
3. Construct an arc above and below the line segment AB by taking B as the center and radius greater than AB/2, and the points C and D will be obtained.
4. Connect C and D and draw a line segment CD.
