As many or as few as you like.
An infinite number. A polygon with any number of sides can be equilateral (ie have sides of equal length).
Anything from none, 2 to 11 sides; and none, 2 to 11 angles. And, the number of equal sides may or may not be the same as the number of equal angles.
4 of them.
Infinitely many. A polygon can have 3 or more sides - there is no upper limit. And for any number of sides, a regular polygon has equal sides.
10 sides and angles * * * * * A decagon need not have any equal sides. If it does have equal sides, their number can take any [integer] value in the range [2, 10].
There need not be any but there can be any number up to ten.
Any number greater than or equal to 3. An isogon is any polygon with equal angles. The name has nothing to do with the number of sides.
a pentagon has 5 sides total, and no parallel sides. A hexagon has 6 sides, so it has 3 parallel sides. any shape with an odd number of equal sides has 0 parallel sides, no matter how many sides it has. every shape with an even number of equal sides will have the # of sides divided by 2 (#/2) of parallel sides.
A pyramid does not need to have any equal sides. A REGULAR pyramid has as many equal sides as the number of sides on the base. So, a triangular pyramid (tetrahedron) will have 3 equal faces, a square based pyramid will have 4, etc.
It has 8 equal sides.
it have 4 equal sides
Any whole number greater than or equal to 3.
