The circle has been known since before the beginning of recorded history.

This relates the circle to a problem in the calculus of variations, namely the isoperimetric inequality.Early science, particularly geometry and astrology and astronomy, was connected to the divine for most medieval scholars, and many believed that there was something intrinsically "divine" or "perfect" that could be found in circles.As proved by Archimedes, in his Measurement of a Circle, the area enclosed by a circle is equal to that of a triangle whose base has the length of the circle's circumference and whose height equals the circle's radius, that is, approximately 79% of the circumscribing square (whose side is of length d).Given a chord of length y and with sagitta of length x, since the sagitta intersects the midpoint of the chord, we know it is part of a diameter of the circle.Since the diameter is twice the radius, the "missing" part of the diameter is (. There are many compass-and-straightedge constructions resulting in circles.By the angle bisector theorem the line segment PC will bisect the interior angle APB, since the segments are similar: Analogously, a line segment PD through some point D on AB extended bisects the corresponding exterior angle BPQ where Q is on AP extended.

Since the interior and exterior angles sum to 180 degrees, the angle CPD is exactly 90 degrees, i.e., a right angle.A circle is a simple closed shape in Euclidean geometry.It is the set of all points in a plane that are at a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves so that its distance from a given point is constant.These points are called the circular points at infinity.In polar coordinates the equation of a circle is: is the distance from the origin to the centre of the circle, and φ is the anticlockwise angle from the positive x-axis to the line connecting the origin to the centre of the circle). r An inscribed angle (examples are the blue and green angles in the figure) is exactly half the corresponding central angle (red).Hence, all inscribed angles that subtend the same arc (pink) are equal.
