a polygon that has all angles congruent is an equiangular .....
A rectangle is a quadrilateral with opposite sides parallel and congruent and four right angles. If all four sides are congruent, it is a square.
A rectangle is a quadrilateral with opposite sides parallel and congruent and four right angles. If all four sides are congruent, it is a square.
Any polygon with an even number of sides (vertices) in which at least one pair of opposite angles are of the same measure.
A polygon with all interior angles congruent Is known as a regular polygon.
It would be an irregular polygon that has not 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.
A four sided polygon where the opposite sides are parallel to each other (they must also by congruent). This also makes the opposite angles congruent. __ /_/ Sort of like that.
