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 triangle.
As many sides as you like providing that it has 3 or more equal sides and equal interior angles
A polygon has as many angles as sides, so a polygon with 10 sides (decagon) would have 10 angles.
There are 5 angles in a polygon with 5 sides.
A polygon has an equal number of sides and angles. For example, a triangle has 3 sides and 3 internal angles.
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.
It is a triangle.
3
No polygon can have less than 3 angles. It would be a triangle with 3 sides but that has 3 angles.
it has 3 sides not 6
A polygon has exactly as many sides as it has angles.
A triangle.
The minimum number of sides for a polygon is 3 sides.
As many sides as you like providing that it has 3 or more equal sides and equal interior angles
A polygon has as many angles as sides, so a polygon with 10 sides (decagon) would have 10 angles.
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.
