The cut is made along the midsagittal plane, which divides the body into equal left and right halves.
To cut a cadaver into equal left and right halves, you would make a sagittal cut along the midline of the body, which runs vertically from the front to the back. This cut divides the body into symmetrical left and right sections. It's important to ensure that the cut is made along the median plane for the halves to be equal.
The Equator divides the Earth into two equal halves, the Northern Hemisphere and the Southern Hemisphere.
midsagittal
You can cut a gold bar into 7 equal parts with 3 cuts by following this method: First, make a cut to create two equal halves of the bar. Next, take one of those halves and cut it into three equal parts. Finally, take the other half and cut it into two equal parts. This results in a total of 7 equal pieces: 3 from one half and 4 from the other half.
