Half Circle Math

A line that just touches the circle as it passes by is called a tangent.

Half circle math.

In geometry the half circle is referred to as the semicircle. Definition of half circle explained with real life illustrated examples. Equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant the distance between any point of the circle and the centre is called the radius this article is about circles in euclidean geometry and in particular the. If it passes through the center it is called a diameter.

A circle is a shape consisting of all points in a plane that are a given distance from a given point the centre. Any diameter of a circle cuts it into two equal semicircles. In mathematics and more specifically geometry a semicircle is a one dimensional locus of points that forms half of a circle the full arc of a semicircle always 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 sometimes used to refer to a half disk which is a two dimensional. A line segment that goes from one point to another on the circle s circumference is called a chord.
