Question

Which of the following alphabet represents a closed curve?
A. U
B. R
C. C
D. O

Answer 1

- Hint: A closed curve is a curve where the beginning and end points are the same. So, in the given option whichever alphabet has the same beginning point and end point represents a closed curve.


Complete step-by-step solution -

The alphabet ‘U’ has one beginning point and one endpoint. So, ‘U’ doesn’t represent a closed curve.
The alphabet ‘R’ has one beginning point and one endpoint. So, ‘R’ doesn’t represent a closed curve.
The alphabet ‘C’ has one beginning point and one endpoint. So, ‘C’ doesn’t represent a closed curve.
The alphabet ‘O’ has the same beginning and end points. So, ‘O’ represents a closed curve.
Thus, the correct option is D. O
Note: The alphabet which represents a closed curve are B and D. The two-dimensional closed curves are circles, triangles, quadrilaterals and polygons etc.
