Question

Which of the following statements are correct?

1. A circle is a type of curve.
2. A triangle has three sides and three angles.
3. A triangle has zero diagonals.

• A. Only 1
• B. 1 and 2
• C. 2 and 3
• D. All of the statements are correct.

Answer 1

The correct option is D All of the statements are correct.

A circle is a closed curve in which every point is at equal distance from the centre.

A triangle has three sides and three angles.

A triangle has zero diagonals. Diagonals must be created across vertices in a polygon, but the vertices must not be adjacent to one another. A triangle has only adjacent vertices.

Hence, all the statements are correct.
