A circular plate has a crack along the line AB, as shown below. A circular plate is shown. The center of the plate is labeled as O. A straight line passes through O and joins the points A and B on the circumference of the plate. If O is the center of the plate, what is the segment AB called? arc of the plate diameter of the plate tangent of the plate circumference of the plate
This is called the diameter of the circular plate. The diameter of a circle is a straight line that passes through the origin with its endpoint are along the circumference of the circle. Thank you and hope this will help you.
