Number of angles in a pentagon
How many angles are there in a pentagon?
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 Ã— 180° – 540°. An octagon has 18 sides and 18 angles and a hexagon has 6 sides and 6 angles.
