Answer
A secant is defined as a line that intersects a circle at exactly two distinct points.
∴ Statement 1 is true.
A radius is a line segment connecting the center of a circle to any point on its circumference.
By definition, all points on the circumference are equidistant from the center, meaning all radii have the same length.
∴ Statement 2 is true.
∴ Both the statements are true.
Hence, option 1 is correct option.
