This is the basic and conceptual question from Chapter name- circles
Topic – Angle properties of circles
Chapter number- 15
In this question, chords AB and CD of the circle are produced to meet at O.
We have to prove that triangles ODB and OAC are similar. It is also given that CD = 2 cm, DO = 6 cm and BO = 3 cm,
We have to find area of quad. CABD. Also calculate AB. Also find (area of CABD) /(area of OAC)
