![]() (10) The circle drawn with hypotenuse of a right angle triangle as diameter, passes through its opposite vertex. i.e the angle subtended by the diameter is always right angle. (9) Angle in a semi circle is a right angle. (8) Angle subtended by an arc in the same segment of the circle are equal. (7) Angle subtended by any arc at the centre of the circle is double the angle subtended by it at any point on the remaining part of the circle. (6) Chords which are at equidistant from the centre of the circle are always equal. (3) Equal chords of the circle are at equal distance from the centre. (5) If angle subtended by the two chord at the centre are equal then the chords are always equal. (4)Equal chord of the circle always subtends the equal angles at the centre of the circle. If AM=MB then OM is perpendicular to the AB.(reference to above fogure) (3) Any line segment joining the centre of the circle and the mid point of the chord is perpendicular to the chord. radius always bisect the chord if perpendicular (2) The perpendicular from the centre of the circle bisect the chord i.e. (1) Of the two chords of the circles, the one which is greater is nearer to the centre. Important theorem and results of the circle: Secant: A line which touch the circle at two distinct points.Ĭhord: A line Segment which lie inside the circle and its end points are always lie on the circle. Tangent: A line which touch the circle at only one point at its circumference. D=2R.ĭiameter is the chord which passes through the centre of the circle.

So, don’t lose the opportunity to grab your govt job with the help of Gradeup. The distance of any point on the circumference of the circle from the centre of the circle is equal.Īre you appearing for SSC CGL Tier-II 2019-20 Exam?

The circle is the most important topic of Geometry. In this article, we will discuss the Circles and various theorem related to it.
