How many degrees is a semi circle
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 has only one line of symmetry (reflection symmetry). In non-technical usage, the term "semicircle" is … See more A semicircle can be used to construct the arithmetic and geometric means of two lengths using straight-edge and compass. For a semicircle with a diameter of a + b, the length of its radius is the arithmetic mean of a and b … See more The equation of a semicircle with midpoint $${\displaystyle (x_{0},y_{0})}$$ on the diameter between its endpoints and which is entirely concave from below is $${\displaystyle y=y_{0}+{\sqrt {r^{2}-(x-x_{0})^{2}}}.}$$ If it is entirely … See more • Semicircle - Mathworld See more An arbelos is a region in the plane bounded by three semicircles connected at the corners, all on the same side of a straight line (the baseline) that contains their diameters See more • Amphitheater • Archimedes' twin circles • Archimedes' quadruplets • Salinon See more WebAngle (Degrees) and Unit Circle.
