Class 9 Maths Circles Circle through 3 points

Circle through 3 points

Let’s draw circles through 1, 2 & 3 points. We can see in the figure that infinite number of circles can be drawn through 1 or 2 points.

Also notice that only one Circle can be drawn using 3 non-collinear points.

Also a circle can’t be drawn using 3 collinear points.

Theorem 5: There is one and only one circle passing through three given non-collinear points.
