In a regular pentagon, there are no right angles. A regular pentagon is one that has 5 equal sides and 5 equal angles. The sum of the 5 angles is 540 degrees. This is found by subtracting 2 from the number of sides and multiplying by 180 degrees. For a regular pentagon the formula would be (5 - 2) * 180 = 540. This works for all polygons. Just replace the 5 with the number of side in the polygon. A good website to visit for this is A non-regular pentagon can have right angles. Home plate on a baseball field would be an example. Original Answer Nope, it has 5 angles of 72 degrees each.
