Question

which circle c shows a chord that is not a diameter?

Explanation:

Step1: Recall definitions

A chord is a line - segment joining two points on the circumference of a circle. A diameter is a chord that passes through the center of the circle.

Step2: Analyze each option

• First option: The line - segment passes through the center, so it is a diameter.
• Second option: The line is a tangent (touches the circle at one point), not a chord.
• Third option: The line - segment is a radius (joins the center to a point on the circle), not a chord.
• Fourth option: The line - segment joins two points on the circle and does not pass through the center, so it is a chord that is not a diameter.

Answer:

The fourth circle shows a chord that is not a diameter.
