Step 1: Investigate the given circle

Step 2: Identify the Center of the circle

NOTE: The middle point, equidistant from all points on the circumference.

It is usually shown by a dot and labelled O.

Step 3: Locate the radius of the circle among the line segments

NOTE: A straight line from the centre to any point on the circle.

Step 4: Find the diameter of the circle.

NOTE: A straight line from one point on the circumference to another,

passing through the centre.

Step 5: Find the Chord of the circle among the line segments.

NOTE: A chord is a line segment with both endpoints on the circle.

The diameter is a special chord that passes through the center of

the circle. The diameter would be the longest chord in the circle.

Step 6: Identify the tangent of the circle

NOTE: A tangent is a line that touches a circle at only one point. A tangent

is perpendicular to the radius at the point of contact. The point of

tangency is where a tangent line touches the circle.
