Question

Three of the following are alike in a
certain way and form a group. Which of
the following does not belong to the
group?
a. Chord
b. Circle
C. Centre
d. Circumference​

Answer 1

Chord doesn't belong to the group. (option a)

• A circle is a closed shape in which all the points lying on the circle are at some fixed distance from a common point.
• This common point is termed as center and the distance from the common point to the boundary of circle is called the radius.
• Circumference is the total length of the boundary of the circle.
• Chord on the other hand, is a line segment joining two points on the circle.

While drawing the circle , we somehow get a glimpse of center and circumference whereas to observe a chord we need to draw a line segment using a ruler. And this separates it out from the rest.
