The diameter of a circle divides it into two halves
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.
diameter
Another name for a circle's line of symmetry is its diameter. A circle has an infinite number of lines of symmetry, all of which pass through its center and can be represented by any diameter. Each diameter divides the circle into two equal halves, demonstrating its symmetric properties.
That line is called a "Diameter".
A half circle is commonly referred to as a "semicircle." It is defined as the shape formed when a circle is divided into two equal halves by a diameter. In geometry, a semicircle includes the curved edge and the straight line segment that forms the diameter.
When a circle is folded along its diameter, it creates two congruent halves or semicircles.

They are over a half an inch (.68) in diameter, round and have two colored halves.
The diameter of a circle is directly proportionate to the circumference. You can find the diameter of a circle by dividing the circumference by the value of Pi (3.14) OR you can find the circumference by multiplying Pi by the diameter. it is a line that halves a circle
