The radius of the compass should equal half the length of the central line. AX is half of the central line’s length and determines the arc’s reach above or below the line.

Class 6 Mathematics Chapter 8 Playing with Constructions question answer
To construct a half-circle, set the compass radius equal to half the central line’s length. Place the compass tip at one endpoint of the central line and draw an arc crossing through AX, which is also half of the line’s length. This ensures symmetry and accuracy. The radius and AX’s alignment are critical in maintaining consistency, creating a smooth curve, and forming the desired geometric pattern.
