When the top of a pencil is cut off, the cut can be described in a few different ways depending on the orientation of the cut:
-
Transverse Plane: This is often used to describe a horizontal cut that divides the object into upper and lower parts. If the pencil is cut horizontally at the top, this would be a transverse cut.
-
Oblique Plane: If the pencil is cut at an angle that is not perfectly horizontal or vertical, then it would be considered an oblique cut.
The other options:
- Parasagittal: This refers to a vertical cut that is parallel to the sagittal plane (which divides the body into left and right). This wouldn't apply to a straight top cut.
- Sagittal or Mid-sagittal: These refer to vertical cuts that divide the pencil into left and right halves, which does not describe a cut made at the top of the pencil.
- Frontal/Coronal: This refers to a vertical cut that divides the pencil into front and back portions. This also does not apply to a cut made at the top.
Therefore, the correct answers in this context would be transverse and oblique.
