Prove that in two concentric circles, the chord of the larger circle, which touches the smaller circle, is bisected at the point of contact.

Explanation

To prove that in two concentric circles, the chord of the larger circle, which touches the smaller circle, is bisected at the point of contact, we can follow these steps:

### Step-by-Step Solution:

1. **Define the Circles and Points**:
Let O be the common center of two concentric circles C1 (the smaller circle) and C2 (the larger circle). Let AB be a chord of circle C2 that touches circle C1 at point P.

**Hint**: Identify the center and the points involved in the problem clearly.
