Answer:
circle - A circle is a shape consisting of all points in a plane that are 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.
radius - a straight line extending from the center of a circle or sphere to the circumference or surface: The radius of a circle is half the diameter.
diameter - In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle.
chord - A line segment connecting two points on a curve. Example: the line segment connecting two points on a circle's circumference is a chord. When the chord passes through the center of a circle it is called the diameter.
1. Circle
circle is all points in the same plane that lie at an equal distance from a center point. The circle is only composed of the points on the border. You could think of a circle as a hula hoop.
2.Radius
radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.[1] The plural of radius can be either radii (from the Latin plural) or the conventional English plural radiuses.[2] The typical abbreviation and mathematical variable name for radius is r. By extension, the diameter d is defined as twice the radius:[3]
3.Diameter
Geometry. a straight line passing through the center of a circle or sphere and meeting the circumference or surface at each end.
or
The diameter is the length of the line through the center that touches two points on the edge of the circle.
4.chord
chord of a circle is a straight line segment whose endpoints both lie on the circle. The infinite line extension of a chord is a secant line, or just secant. More generally, a chord is a line segment joining two points on any curve, for instance, an ellipse. ... The word chord is from the Latin chorda meaning bowstring.
