Given:
Center of circle = Point O.
Let's use the image to identify line IE.
Since E is the center of the circle and point I is on the circumference of the circle, line IE starts from the point I and goes to the center of the circle, point E.
Hence, we can say line IE is the radius of the circle.
The radius of a circle can be said to be the distance from the center of a circle to any point on the circumference of the circle.
Therefore, IE is the radius of the circle.
