Q: 2 A chord of a circle is equal to the radius of the circle. Find the angle subtended by the chord at a point on the minor arc and also at a point on the major arc.
Given: A chord of a circle is equal to the radius of the circle i.e. OA=OB.
To find: ADB and ACB.
OA = AB (Given )
OA = OB (Radii of circle)
ABC is a equilateral triangle.
AOB = 2 ADB
ACBD is a cyclic quadrilateral .
So, ACB+ADB =
