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

• A. Half-Circle
• B. Circle
• C. Triangle
• D. Square

Answer: (A)

The main idea here is distributing hair evenly from a central point by using a curved, radial parting. A semicircular (half-circle) shape lines up with the head’s natural curve and lets you divide the hair into equal angular portions around that center. As you lift and cut, each section uses a similar amount of hair, giving a balanced result around the origin. Using a full circle isn’t practical on a real head because you can’t access every direction equally, and triangular or square shapes create straight-edged sections that don’t radiate evenly from one center, which leads to uneven proportions. So, the semicircular shape best achieves equal proportions from a central origin while fitting the head’s contour.
