Types of Pentagons

• Regular or equilateral pentagon: five equal sides and angles.
• Irregular pentagon: five unequal sides and unequal angles.
• Convex pentagon: no internal angle can be greater than 180 degrees.
• Concave pentagon: has an internal angle greater than 180 degrees causing two sides to “sink in” like a “cave”
