Question

The least number of non-collinear points required to draw a unique circle passing through them is:

• A. 2
• B. 3
• C. 4
• D. 5

Answer 1

The correct option is B

3

For drawing a unique circle, we need 3 non-colinear points. Passing with 2 points or 1 point, we can draw infinite circles. This can be understood by the concept that every triangle has a unique circumcircle with the center as circumcentre.
