What is circle class 10th?
Circle: A circle is a collection of all points in a plane which are at a constant distance from a fixed point. Centre: The fixed point is called the centre. Radius: The constant distance from the centre is called the radius. Chord: A line segment joining any two points on a circle is called a chord.

What is circle and its types?
In Maths or Geometry, a circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident. A circle is also termed as the locus of the points drawn at an equidistant from the centre. The distance from the centre of the circle to the outer line is its radius.
What is special about circle?
Properties. The circle is the shape with the largest area for a given length of perimeter (see Isoperimetric inequality). The circle is a highly symmetric shape: every line through the centre forms a line of reflection symmetry, and it has rotational symmetry around the centre for every angle.
What is the theorem 10.2 Class 10?
Class 10 Theorem 10.2 The lengths of tangent drawn from an external point to a circle are equal. Class 10 Theorem 10.2 The lengths of tangent drawn from an external point to a circle are equal.
What are the properties of circle Class 10?
Circle Properties
- The circles are said to be congruent if they have equal radii.
- The diameter of a circle is the longest chord of a circle.
- Equal chords of a circle subtend equal angles at the centre.
- The radius drawn perpendicular to the chord bisects the chord.
- Circles having different radius are similar.
Who defined circle?
Apollonius of Perga showed that a circle may also be defined as the set of points in a plane having a constant ratio (other than 1) of distances to two fixed foci, A and B. (The set of points where the distances are equal is the perpendicular bisector of segment AB, a line.)
What is a circle in math?
A circle is the set of all points in the plane that are a fixed distance (the radius) from a fixed point (the centre). Any interval joining a point on the circle to the centre is called a radius. By the definition of a circle, any two radii have the same length.
