The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting. A self-intersecting regular pentagon (or star pentagon) is called a pentagram. A pentagon is a 5-sided Polygon (a flat shape with straight sides): Regular or Irregular When all angles are equal and all sides are equal it is regular, otherwise it is irregular: Concave or Convex A convex pentagon has no angles pointing inwards. More precisely, no internal angles can be more than 180°. Visa mer A convexpentagon has no angles pointing inwards. More precisely, no internal angles can be more than 180°. When any internal angle is greater than 180° it is concave. (Think: concave has a "cave" in it) Visa mer A regularpentagon has: 1. Interior Angles of 108° 2. Exterior Angles of 72° 3.
