Question

is the following biconditional true? a line segment is a diameter of a circle if and only if its endpoints are on that circle. yes no submit

Explanation:

A diameter is a line segment passing through the center of the circle with endpoints on the circle. Just having endpoints on the circle is not sufficient (e.g., a chord that is not a diameter also has endpoints on the circle). So the biconditional is false.

Answer:

no
