a diameter for a circle possibly a bisector for other shapes
The other name for the line of symmetry of a circle is the diameter. The diameter of a circle is a line segment that passes through the center of the circle and has endpoints on the circle itself. It divides the circle into two equal halves, making it a line of symmetry. This means that if you were to fold the circle along the diameter, both halves would perfectly overlap.
The 2 halves in a circle are the 2 semi circles.
They occur when you divide something on a line of symmetry.
a semi - circle has zero parallel lines
