Question

How many diagonals does the following have: A triangle

Answer 1

Estimate the number of diagonals:

1. A line segment joining the two vertices of a polygon is called a diagram.
2. The given polygon is a triangle.
3. Therefore, we can see that constructing a diagonal for a triangle is not possible from the following diagram.
4. From the diagram, we can count that there are zero diagonals.

Hence, there are zero diagonals in a triangle.
