Answer 2

The correct answer is (1) Convex

A convex polygon is defined as a polygon with all its interior angles less than 180°. This means that all the vertices of the polygon will point outwards, away from the interior of the shape.

Think of it as a 'bulging' polygon.All the diagonals of a convex polygon lie entirely inside the polygon.
