M L Aggarwal Solutions for Chapter: Circle, Exercise 2: Objective Type Questions

The diameters of a circle are concurrent. The centre of the circle is the point common to all diameters.

Every circle has a unique centre and it lies inside the circle.

Every circle has a unique diameter.

From a given point in the exterior of a circle, two tangents can be drawn to it and these two tangents are equal in length.

If $P$ and $Q$ are any two points on a circle, then the line segment $PQ$ is called a

If $P$ is a point in the interior of a circle with centre $O$ and radius $r,$ then 

If $AB=12 \mathrm{cm},BC=16 \mathrm{cm}$ and $AB$ is perpendicular to $BC$, then the radius of the circle passing through the points $A,B$ and $C$ is

In the given figure, $AB$ is a diameter of the circle. If $AC=BC$, then $\angle \mathrm{CAB}$ equal to
