What is meant by centre of symmetry?

Explanation

### Step-by-Step Text Solution:

1. **Definition of Center of Symmetry**:
The center of symmetry refers to a point within an object such that for every point in the object, there is an equivalent point at an equal distance on the opposite side of the center. This means that the object is symmetrical about that point.

2. **Understanding with Examples**:
- **Circle**: Consider a circle. If you draw a line through the center of the circle, it divides the circle into two equal halves. Each half is a mirror image of the other. Therefore, a circle has a center of symmetry at its center point.
- **Alphabet Example**: Take the letter "A". If you draw a vertical line down the center of "A", it divides the letter into two equal parts that are symmetrical. Thus, "A" has a center of symmetry along that vertical line. However, if you draw a line horizontally across "A", the two halves will not be identical, indicating that "A" does not have a center of symmetry in that orientation.
