Answer:
Segment AB is called the Radius.
Step-by-step explanation:
We are given a circular plate which has a crack along the line AB.
The center of the plate is labeled as A and B is a point on the circumference of the plate.
Now we are asked to find what the line segment AB is called.
We know that radius of a circle is a line segment that joins the center of the circle to any point on the circumference of the circle.
Here we have Point A is the center and B is the point on the circumference.
Hence, Line AB is called the Radius of the circle.
