Mathematics for all. Search this site. Tangent to a circle A line that touches a circle at only one point is called the tangent to the circle. TAU is tangent to the circle. Facts about tangents One and only one tangent can be drawn to a circle from a point on it.

A circle is a shape consisting 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 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 Euclidean plane, except where otherwise noted. Specifically, a circle is a simple closed curve that divides the plane into two regions : an interior and an exterior. In everyday use, the term "circle" may be used interchangeably to refer to either the boundary of the figure, or to the whole figure including its interior; in strict technical usage, the circle is only the boundary and the whole figure is called a disc. A circle may also be defined as a special kind of ellipse in which the two foci are coincident and the eccentricity is 0, or the two-dimensional shape enclosing the most area per unit perimeter squared, using calculus of variations.

The common distance of the points on the curve from the center is called the radius. The region bounded by the circle is also often referred to as a circle as in when we speak of the area of a circle , and the curve is referred to as the perimeter or the circumference of the circle. Your email address will not be published. The radius of the circle is a straight line drawn from the center to the boundary line or the circumference. The plural of the word radius is radii. The diameter is the line crossing the circle and passing through the center.

A circle is a closed shape formed by tracing a point that moves in a plane such that its distance from a given point is constant. The word circle is derived from the Greek word kirkos, meaning hoop or ring. When a set of all points that are at a fixed distance from a fixed point are joined then the geometrical figure obtained is called circle. Radius is the fixed distance between the center and the set of points. Diameter is a line segment, having boundary points of circles as the endpoints and passing through the center. So, the length of the circle or the perimeter of the circle is called Circumference.

Как у всех молодых профессоров, университетское жалованье Дэвида было довольно скромным. Время от времени, когда надо было продлить членство в теннисном клубе или перетянуть старую фирменную ракетку, он подрабатывал переводами для правительственных учреждений в Вашингтоне и его окрестностях. В связи с одной из таких работ он и познакомился со Сьюзан. В то прохладное осеннее утро у него был перерыв в занятиях, и после ежедневной утренней пробежки он вернулся в свою трехкомнатную университетскую квартиру.
