Explanation
Let us see some definitions:
• A ,radius, is a segment line from the center to a point on the circle.
,
• A ,diameter ,is a segment line from one side of the circle to the other, going through the center.
,
• A ,chord, is a line segment joining any two points on the circumference of the circle.
,
• A line, tangent ,to a circle is a line that touches the circle at only one point.
As we can see in the question, the segment AC is a line segment that joins two points on the circumference but does not pass through the center of the circle. Therefore, the segment AC is a chord.
