Question: How do you know if a curve is closed?

What does a closed curve look like?

How many types of curve are there?

Question 3: What are the types of curves? Answer: The different types of curves are Simple curve, Closed curve, Simple closed curve, Algebraic and Transcendental Curve.

Are shapes which are strong and do not change?
