A Closed Curve is a curve with no endpoints.
In a closed curve the starting point is always joined to the endpoint.
The figures shown above are closed curves.
A.Figure 1
B.Figure 2
C.Figure 3
D.Figure 4
Correct Answer: A
Step 1: A closed curve is a curve with no endpoints.
Step 2: Here, Figure 2, Figure 3, and Figure 4 have the same starting and ending points but only in Figure 1, the starting and stopping points are different.
Step 3: So, Figure 1 is not a closed curve.
