This MCQ is based on the Basic concepts of Circles.
This includes chord and its theorem, inscribed, diameter, radius, area, and the angle subtended by the diameter of the circle.
A chord is at a distance of 8 cm from the centre of a circle of radius 17 cm. The length of the chord is
AB and CD are two equal chords of a circle with centre O such that ∠AOB = 80°, then ∠COD =
An equilateral triangle of side 9 cm is inscribed a circle. The radius of the circle is
Sides AB and AD of a quadrilateral ABCD are produced to E and F respectively. If ∠CBE = 100°, then find ∠CDF.
D is diameter of a circle and AB is a chord. If AD = 50 cm, AB = 48 cm, then the distance of AB from the centre of the circle is
In a circle with center O and a chord BC, points D and E lie on the same side of BC. Then, if∠BDC=80°, then ∠BEC =
The center of the circle lies in______ of the circle.
If chords AB and CD of congruent circles subtend equal angles at their centres, then:
The longest chord of the circle is:
If there are two separate circles drawn apart from each other, then the maximum number of common points they have:
The angle subtended by the diameter of a semi-circle is:
If a line intersects two concentric circles with centre O at A, B, C and D, then:
ABCD is a cyclic quadrilateral such that AB is a diameter of the circle circumscribing it and ∠ADC = 140º, then ∠BAC is equal to:
