Which shape is used to move the hair in equal proportions from a center point of origin?

• A. Half-Circle
• B. Circle
• C. Ellipse
• D. Rectangle

Answer: (A)

Moving hair in equal proportions from a center origin relies on sectioning that follows a curved path around the center. A semicircular shape provides a consistent arc for pulling and distributing hair so each segment along that arc is equally spaced from the center. This gives uniform control of density and angle as you work outward. Using a full circle would spread hair in all directions and complicate the section within the intended working area, making it hard to maintain equal proportions in the desired plane. An ellipse would distort equal spacing because the arc stretches more in one direction, and a rectangle creates angular, non-radial sections that don’t radiate evenly from the origin. Therefore, the semicircle is the shape that best yields equal proportions from the center in this technique.
