In the figure below, `bar(MN)` is the diameter of the circle with centre O. `bar(NP)` bisects the `/_ANM`. If `/_ NMA =33^(@)`, then find `/_ ANP`.

In the figure given below,AD is a diameter of a circle with centre O.If AB II CD,prove that AB=CD

In the above figure (not to scale), O is the centre of the circle. bar(BC) and bar(CD) are equal chords. If /_ OBC =70^(@) , then find /_BAD .

In the figure given below, AB is the diameter of the circle whose centre is at O. Given that angleECD=angleEDC=32^(@) , then angleCEFandangleCOF respectively are

In the figure below, CD is a chord of the semi circle with centre O. OA is the radius of the circle. If CD=10 cm, AB=2 cm and bar(OA)_|_bar(CD) the length of OB is "_____________"

In Figure,AB=CB and O is the centre of the circle.Prove that BO bisects /_ABC .

In given figure, O is the centre of the circle. A chord, which is not the diameter of the circle is

In the figure below (not to scale), bar(MR )_|_ bar(MP), bar(MQ) _|_ bar(MN) , and bar(MS) is bisector of /_ RMQ . If /_ PMN=50^(@) , then find the measure of /_ RMS .

In the given figure, O is the centre of the circle. Name a chord, which is not the diameter of the circle.

In the adjoining figure, seg MN is a chord of a circle with centre O . l(MN) = 25 . Point L on chord MN such that l(MN)=9 and l(OL)= 5, then find radius of the circle.
