Key Points: Some Important Results on Circles
-
Intersecting Circles (Collinearity):
If two circles with centres O and O′ intersect at two points and diameters are drawn through these points, then the given points lie on a straight line. -
Cyclic Parallelogram:
Every parallelogram inscribed in a circle is a rectangle. -
Isosceles Trapezium:
An isosceles trapezium is always a cyclic quadrilateral. -
Cyclic Trapezium Properties:
A cyclic trapezium is isosceles, and its diagonals are equal. -
Regular Polygon:
Any four vertices of a regular polygon lie on a circle. -
Chords Bisecting Each Other:
If two chords of a circle bisect each other, then both the chords are diameters of the circle. -
Angle Bisectors of a Cyclic Quadrilateral:
The quadrilateral formed by the angle bisectors of a cyclic quadrilateral is also cyclic. -
Mid-point of Hypotenuse:
The mid-point of the hypotenuse of a right-angled triangle is equidistant from all three vertices of the triangle. -
Equal Chords and Angles at the Centre:
In a circle, equal chords subtend equal angles at the centre. -
Converse of Equal Chords Theorem:
In a circle, chords which subtend equal angles at the centre are equal in length.
