A convex polygon with congruent sides and congruent angles is a regular polygon.
Some regular pilgrims have specific names: Equilateral triangle and square
a polygon with 4 right angles and 4 sides of the same length
any regular polygon
A polygon with 2n sides (n>1) can have opposite angles congruent.
Not all polygons are regular by definition. An irregular polygon may have non-congruent sides or non congruent angles or both. A regular polygon will always have both congruent sides and angles.
Any polygon with 2n sides (n integer) where opposite sides are parallel, will have its opposite angles congruent.
Not necessarily. A convex heptagon is a polygon but it need not have all sides and angles congruent.
yes
congruent; congruent
true
Yes
with all sides equal (congruent) AND all angles equal (congruent). In these circumstnces the adjective "convex" is redundant.
True. A convex polygon with more than four sides that has congruent interior angles must also have congruent sides, making it a regular polygon. Regular polygons are defined by having both equal angles and equal side lengths. Therefore, if a convex polygon has congruent interior angles, it is necessarily regular.
Convex polygons with congruent sides and congruent angles are called regular polygons.
That is called a regular polygon.
It would be an irregular polygon that has not congruent sides and angles
That doesn't have a special name. If all the angles are also congruent (and convex), then it is called a regular polygon.
Regular polygons have congruent sides and angles
