In Fig. 16.202, O is the centre of the circle such that ∠AOC=130°, then ∠ABC=

We have,

∠AOC = 130°

∠ABC = * (Reflex of AOC)

= * (360^o – 130^o)

= * 230

= 115°

Angle formed in minor segment of a circle is

Number of circles that can be drawn through three non-collinear points is

In Fig. 16.203, if chords AB and CD of the circle intersect each other at right angles, then x + y =

In Fig. 16.204, if ∠ABC= 45°, then ∠AOC=
