The horizontal mid-line that intersects the midpoint of the B measurement is called which measurement?

• A. A Measurement
• B. Dbl
• C. Geometric Center
• D. C Measurement

Answer: (D)

In this measurement scheme, B provides a baseline, and the horizontal line that passes through the midpoint of that baseline is designated as the C measurement. This midline creates a stable reference axis for describing other features, so it’s named to reflect its role as the central cross-line through B. The other terms don’t fit this description: an A measurement would imply a different axis or distance, “Dbl” isn’t a standard midline designation, and the geometric center refers to a central point rather than a line. So the horizontal mid-line intersecting B’s midpoint is the C measurement.
