Given:
Center of cirlce = Point E.
Let's use the given figure to identify the line AC.
Here, we can see that points A and C lie on the circumference of the circle without passing through the middle.
Since they lie on the circumference and connect the point AC, we can say line AC is a chord.
A chord can be said to be a line segmenet which joins two points on the circumference of the circle.
Therefore, AC is a chord.
