Which method determines head gore length?

• A. Center of head to tangent line
• B. Edge of head to tangent line
• C. Diameter of head
• D. Distance from tangent to edge

Answer: (A)

Gore length is determined by the distance from the center of the head to the line where the head’s contour becomes tangent to the seam boundary. The gores are wedge-shaped pieces that radiate from the head’s centerline, so the measurement that defines how long each gore should be is the radius from the center to that tangent boundary. This ensures the piece wraps smoothly around the curved surface and aligns with the boundary where the pattern ends. Measuring from the edge to a tangent line would not reflect the wedge’s proper span, and using the diameter or a distance from tangent to edge would double-count or miss half of the needed length. So the center of the head to the tangent line gives the correct gore length.
