This is a rather vague question, and I'm not exactly sure what you are trying to ask, but if I guessed correctly..... Congruent means that everything is equal in comparison. There are many possible rectangle dimensions, so they all are not congruent. I hope this is what you want to ask.

No, rectangles do not have congruent sides. Squares have congruent sides.

Why Can all rectangles be cut in half vertically or horizontally to make to congruent rectangles?

They make two congruent rectangles, not to rectangles! This is because the line joining the midpoints of opposite sides are lines of [reflective] symmetry.

Can a rectangle be a square explain?

a rectangle has 4 right angles. A rhombus has four congruent sides. A square has four right angles and four congruent sides. All squares are rectangles because all rectangles have 4 right angles, and all squares have four right angles. But not all rectangles are squares because not all rectangles have congruent sides.

Because there opposite sides are congruent. And all squares are rectangles, but not all rectangles are squares!

What is a 3 dimensional figure that has three pairs of opposite parallel congruent faces that are rectangles?

This depends on if the question is asking for each pair of opposite rectangles must be congruent, then it is a rectangular prism.If all of the rectangles are congruent, then it must be a Cube. A square is a special case of a rectangle, and all 6 sides being squares makes a cube and they are all congruent.
