- ABC is an isosceles triangle with ab = AC and angle BAC is equal to 40 degree list of a circle passing through B and C intersect side a b and ac at the point B and D respectively
-
AB is chord of a circle with centre O. Let P and T be two points on the circumpherence such that < APB # < ATB and < APB = 80 degree then what is the value of < ATB.
- if a segment contains more than two angles even then all of them will be equal?
- prove that a cyclic parallelogram is a rectangle
- Prove that the opposite angles of a cyclic quadrilateral are supplementary.
