Answer:
1. True
2. False
3. True
4. False
5. True
Step-by-step explanation:
1. Consecutive sides have the same endpoint creating and angle, therefore true.
2. This is only true for the quadrilaterals but not all polygons.
3. Since what is mentioned is a regular polygon, they are equiangular and equilateral, then they would create congruent angles.
4. Exterior angles of a polygon are the angles formed when the side of a polygon is not extended.
5. As mentioned in no.3, being equiangular and equilateral would deem all interior angles congruent.
