Congruent
Two pairs. Again, this is not an "improvement" on that answer, just an elaboration. The dictionary defines, in geometry, a 'square' as a rectangle having all four sides of equal length. Therefore two pairs of parallel sides as the person said.
If all three sides are equal in length, the triangle is said to be Equilateral.
They both have 3 sides but an isosceles triangle has two equal sides whereas an acute triangle with different acute angles has no equal sides and is said to be a scalene triangle, or an acute triangle with three equal acute angles (of 60° each) and three equal sides is called an equilateral triangle.
if two sides are of equal length, the a triangle is said to be isoceles.
The ratios of all three corresponding sides is ALWAYS equal. But there is nothing that can be said about parts of the sides.

A two sided polygon is called a bigon, and it exists in spherical geometry. (the previous answerer said this: "a polygon has 3 or more sides retard idiot so how stupid can you be a polygon can not have 2 sides dumb*ss" - and I would advise him/her to shout at the mirror next time)

No, it does not. A polygon is an enclosed plane area whose boundaries comprise straight lines. There is no requirement for the sides to be equal. If they are, the polygon is said to be equilateral.
the last person who answered this said pentagon, but there isn't a correct answer for this. A square would be the closest, but it has FOUR equal sides.
They are said to be similar
In geometry, it refers to two shapes that are identical in shape and size. If one shape can be moved - without stretching or cutting - so that it exactly covers another, then the two shapes are said to be congruent.
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.
Yes in general polygons that have equal interior angles also have equal sides and they are said to be regular polygons. But a rectangle is an exception.
