Question

If each angle of a polygon is less than ${180}^o$ then it is called a ____ polygon.

• A. concave
• B. irregular
• C. convex
• D. None of the above

Answer 1

Answer: (C)

convex

All the diagonals are in the interiors of the polygons because each angle is less than ${180}^o$. So, It has no reflex angle.
Therefore, C is the correct answer.
