Yes, a butterfly's body can be externally divided into equal halves through a plane passing through the center, a characteristic known as bilateral symmetry. While the two halves may appear mirror images of each other, butterflies do not have a distinct right or left side due to this symmetry. This allows for balanced development and efficient movement in their environment.
Right, or left hemisphere.
Four axes of symmetry: vertical axis, horizontal, positive diagonal (bottom left to top right) and negative diagonal (top left to bottom right). In fact, any straight line through the centre of the square divides it into two halves so there are an infinite number of ways, not just four. And the above are without looking at symmetric curves through the centre of the square.
A bisector is a line that divides another into two halves. If the second line is at right angles to the first, it is perperdicular. So, a perpendicular bisector of a side is a line which is at right angles to the side and which divides the side into two halves.
The cut is made along the midsagittal plane, which divides the body into equal left and right halves.
The body is divided into equal vertical left and right halves by the sagittal plane.
Bilateral symmetry divides an organism into left and right halves.

The sagittal plane can divide the body into left and right unequal halves.

Two equal angles would be the result
Yes, the superior plane divides the body into upper and lower halves, not right and left halves. The right and left halves are divided by the midsagittal plane.
No. Spiders have a clear "front" and "back" which are not interchangeable. Consequently they have a clear "right" and "left" side.
The sagittal planed divide the body into left and right portions, and specifically the midsagittal plane divides the body into equal left and right halves.
