hexagon
Such a polygon is said to be a "regular" polygon, meaning that all its sides are equal and all its angles are equal, so we have; equilateral triangle; square; pentagon; hexagon; heptagon;octagon;nonagon;decagon - to give but the first nine possibilities. The next one would have 11 equal sides and angles, and I don't know its name.
It is called a quadrilateral. This is the general term for a four-sided polygon, but if at least two sides are equal or two angles are equal, it has a more specific name.
Equilateral triangle.Also a square.Also a regular pentagon.Also any regular polygon of any number of sides.A shape with equal sides and angles is a called a regularshape.[But there are also other shapes, such as a rhombus, which has equal sides but is not a regular polygon because it does not have equal angles. There is no collective name for such "squashed" polygons".]
There is no specific name, except in the case of a triangle: scalene. You should not call it simply an irregular polygon, because a regular polygon implies that ALL sides are equal and ALL angles are equal. So a rhombus, where all four sides are equal, is still irregular.
That is called a regular polygon.
There is no special name for that. However, if the sides are also equal, it is called a regular polygon.
That would be called a regular polygon, one with congruent(equal) side legnths and congruent angles.
square?
A regular hexagon which has 6 equal sides and 6 equal angles.
It is usually a regular polygon that has equal sides.
pentagon
hexagon
A rhombus
Square.
Scalene quadrilateral is a polygon that has no congruent sides.
If a polygon's sides are all of equal length, it is known as a regular polygon. (The measure of each of its angles will be the same as well)
