Not necessarily.
Same-side interior angles are supplementary. They are not always congruent, but in a regular polygon adjacent angles are congruent.
It is a regular polygon providing that its interior angles are equal as well.
a "regular" one
No. You also need all of the sides to be congruent. For example, a rectangle has four congruent angles, but it is not a regular polygon.
A regular polygon
A polygon with all interior angles congruent Is known as a regular polygon.
A regular polygon is a polygon with congruent sides and interior angles.
Yes and providing that its interior angles are congruent as well because whilst a square is a regular polygon a rhombus is not a regular polygon although it has 4 equal sides its interior angles are not congruent.
A polygon with all sides congruent is a square.
Same-side interior angles are supplementary. They are not always congruent, but in a regular polygon adjacent angles are congruent.
It is a regular polygon providing that its interior angles are equal as well.
a "regular" one
Regular polygons have congruent sides and angles
No. You also need all of the sides to be congruent. For example, a rectangle has four congruent angles, but it is not a regular polygon.
Any regular polygon has this property, as does any rectangle.
A regular polygon has congruent sides and equal interior angles such as a square or an equilateral triangle
