That depends somewhat on other characteristics of the polygon.
-- If it has four sides and one pair of them is parallel and congruent, then the
other pair must also be parallel and congruent, and it's called a parallelogram.
-- If it has four sides, parallel and congruent opposite sides, and a right angle,
then it's called a rectangle.
-- If it has four sides and all four sides are congruent, then opposite sides must be
parallel, and it's called a rhombus.
-- If it has four sides and both pairs of sides are parallel and all four are congruent
and it has a right angle, then it's called a square as well as a rhombus.
-- Any polygon with more than four sides can have at least one pair of opposite
parallel congruent sides and possibly more, but doesn't necessarily have.
-- If it's a regular polygon, then it has one or more such pairs of sides if, and only if,
it has an even number of sides.
-- In any case with more than four sides, the polygon is named for its number of sides.
And I believe that pretty well covers it.
What else can I help you with?
What is a four-sided polygon quadrilateral with all sides congruent opposite sides parallel called?
A square or a rhombus
Is it true that in a polygon all sides are congruent and all angles are congruent?
No, it is not true that in a polygon all sides and angles are congruent. A polygon with all sides congruent is called a regular polygon, but there are also irregular polygons where the sides and angles can vary. For example, a rectangle has congruent opposite sides but not all sides are equal, and its angles are congruent but not all angles need to be equal in other types of polygons. Thus, congruence in sides and angles only applies to regular polygons.
If a polygon has all congruent sides and angles what is it called?
