Definitions

semicircle

A building plan shaped like a circle cut in half.

A semicircle is a shape formed by one straight side and one arc. It may be an exact half-circle, a thin slice of a circle's or oval's edge, or a bulbous shape with a prominent straight edge. It cannot be more than 75% of a complete circle by total area, or of a complete oval if the completed perimeter would form an oval.

Any side of a semicircle can have slight irregularities as long as the whole shape produces the general impression of a semicircle. The circular side can be composed of multiple straight lines that meet at oblique angles.
