Step 1: Understanding the Shape of a Circle.
A circle is defined as a shape where all points are equidistant from a central point. The shape of a circle is round and does not have straight edges or vertices.
Step 2: Verifying the Options.
- Option (1): A triangle has three straight sides and vertices, which is not the shape of a circle.
- Option (2): A circle is defined by its round shape, so this is the correct answer.
- Option (3): A square has four equal straight sides, not the shape of a circle.
- Option (4): An inverted triangle is not a circle.
Conclusion:
Therefore, the correct answer is (2) figure of Circle.
