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.
