A polygon has 3 or more sides and is called regular when all sides and angles are equal and it is irregular when its sides and angles are not equal.
As many sides as you like providing that it has 3 or more equal sides and equal interior angles
No, but an equilateral triangle is a regular polygon with 3 equal sides and 3 equal angles.

An irregular polygon with 5 or more sides.
A polygon has 3 or more sides and is called regular when all sides and angles are equal and it is irregular when its sides and angles are not equal.
A polygon has an equal number of sides and angles. For example, a triangle has 3 sides and 3 internal angles.

An equilateral triangle
No, but an equilateral triangle is a regular polygon with 3 equal sides and 3 equal angles.

An isosceles triangle
A polygon that has congruent sides and congruent angles is called a Regular polygon. If the number of sides is given, you can be more specific. Some examples: 3 congruent sides/angles = equilateral triangle 4 congruent sides/angles = square 5 congruent sides/angles = regular pentagon 6 congruent sides/angles = regular hexagon ...and so on, by adding "regular" in front of the shape's name.
An Isosceles triangle.
The polygon can have any amount of sides as the sum of the interior angles is always equal to the sum of its interior angles. For example, 0=0, 1=1, 2=2, 3=3.Another answer:It will have four sides.
An irregular polygon with 5 or more sides.
An isosceles triangle is not a regular polygon because it has only 2 equal sides but an equilateral triangle is a regular polygon because it has 3 equal sides and 3 equal angles.
