Semicircle. A semicircle is half of a circle. It resembles a round paper plate folded in half. An arc on a circle that has endpoints that lie on a diameter of the circle is a semicircle.
A semicircle is half of a circle. It is a 2D shape formed when a circle is cut into two equal parts. We can create two semi-circles from any circle. Some of the real-life examples of a semicircle are the shape of a protractor, the shape of a round paper folded in half, etc.
In mathematics (and more specifically geometry), a semicircle is a one-dimensional locus of points that forms half of a circle. It is a circular arc that measures 180° (equivalently, π radians, or a half-turn). It only has one line of symmetry (reflection symmetry).

In geometry, a semicircle is defined as a half circle formed by cutting the circle into two halves. It is formed when a line passes through the center and touches the two ends of the circle. This line is called the diameter of the circle.
A semicircle is a half circle, formed by cutting a whole circle along a diameter line, as shown above. Any diameter of a circle cuts it into two equal semicircles. * An alternative definition is that it is an open arc.
A semicircle is essentially half of a circle. Drawing a diameter across a circle effectively divides it into two equal halves, each being a semicircle. The circumference of a semicircle is simply half that of the full circle. Sc = π⋅r S c = π ⋅ r.
