# Let A, B be the centres of the two circles of equal radii; draw them so that each one of them passes through the centre of the other. Let them intersect at C and D. Examine whether AB and CD are at right angles.

**Solution:**

We will be using the concept of circle to solve this.

In the above figure, two circles with center A and B of equal radii intersect each other at C and D. We can say that the AB and CD are perpendicular and intersect at 90 degrees.

## Let A, B be the centres of the two circles of equal radii. Draw them so that each one of them passes through the centre of the other. Let them intersect at C and D Examine whether AB and CD are at right angles.

**Summary:**

Two circles of equal radii with centers A and B are drawn such that each one of them passes through the center of the other, and they intersect at C and D. AB and CD are perpendicular to each other and are at right angles.
