Question

Using the information given in the figure, which of the given option(s) show $\Delta ABC$ with all three vertices on the circle and equal in area to $\Delta OAB$?

• A.
• B.
• C.
• D.

Answer 1

Answer: (A), (D)

The correct options are
A

D

Draw a diameter through O parallel to AB. Take any one of the endpoints of the diameter and join it to points A and B. The newly formed $\Delta ABC$ has all three vertices on the circle and has the same area as $\Delta OAB$.
