Answer:
Step-by-step explanation:
In a circle, a radius is a line segment that connects the center of the circle to any point on the circumference. To identify a segment that is a radius, we need to find a line segment that starts from the center of the circle and ends at a point on the circumference.
To determine if a segment is a radius, we can follow these steps:
Locate the center of the circle. The center is usually denoted as point O.
Identify a point on the circumference of the circle. Let's call this point A.
Draw a straight line from the center (O) to the point on the circumference (A).
Measure the line segment from the center to the point on the circumference.
If the length of the line segment is the same as other line segments drawn from the center to different points on the circumference, then it is a radius.
The reason we can determine if a segment is a radius is because all radii of a circle are equal in length. This is a fundamental property of circles. So, if we find a segment that has the same length as other segments drawn from the center to different points on the circumference, we can confidently say that it is a radius.
Remember, a radius is always a straight line that connects the center of the circle to a point on the circumference.
