Question

What is the line of symmetry of the circle called?

• A. $Radius$
• B. $Diameter$
• C. $Chord$
• D. $Secant$

Answer 1

The correct option is B

$Diameter$

Since the line of symmetry passes through the center of the circle.

Hence, $Diameter$is the line of symmetry of a circle.

$Radius$of a circle doesn't intersect the circle at two points. So, $Radius$is not a line of symmetry for a circle.

It is not necessary that $Chord$pass through the center of the circle. So, $Chord$is not a line of symmetry for a circle.

$Secant$intersects the circle at two points but it is not necessary to pass through the center of the circle. So, $Secant$is not a line of symmetry for a circle.

Hence, $Diameter$is the line of symmetry of a circle.
