Number of angles in a pentagon

How many angles are there in a pentagon?

5

It is important to know the fact that a polygon has as many angles as it has sides.  For example, a triangle has 3 sides and 3 angles.  Needless to say, a pentagon has 5 sides and 5 angles.  Keep in mind the fact that a pentagon has 5 sides.  Moreover, it can be made from three triangles.  It is interesting to know that its interior angles add up to 3 × 180° – 540°. An octagon has 18 sides and 18 angles and a hexagon has 6 sides and 6 angles.
