Do all pentagons have congruent angles?
Yes providing that they are regular 5 sided pentagons otherwise no if they are irregular pentagons
What are all the types of pentagons?
Pentagons can be classified based on their side lengths and angles. The main types include regular pentagons, which have all sides and angles equal, and irregular pentagons, which have sides and angles of varying lengths. They can also be categorized as convex pentagons, where all interior angles are less than 180 degrees, and concave pentagons, which have at least one interior angle greater than 180 degrees. Additionally, pentagons can be further classified into specific types like cyclic pentagons, which can be inscribed in a circle, and self-intersecting pentagons, also known as star pentagons.
Why can't you use regular pentagons to tile an area?
Because There is always the little sliver that it doesnt cover
