Two polygons are similar if and only if the corresponding angles are congruent
polygons that have corresponding angles congruent and corresponding sides proportional
No, you cannot.
Similar polygons are polygons for which all corresponding angles are congruent and all corresponding sides are proportional. From this definition we can say they have the same shape.
Polygons that have the same shape and size and all corresponding parts are congruent. (angles and sides)
No, the definition of congruent polygons is that all corresponding SIDES are of equal length. All corresponding angles as well.
No. The word congruent is not applied to sides or angles.
Angles are congruent if they are equal. Corresponding angles in figures that are similar are congruent.
