No, rectangles do not have congruent sides. Squares have congruent sides.
A hexagonal prism.
Isosceles trapezoids, squares, and rectangles.
Yes
A prism??? O.o sounds like it to me anyway...
yes rectangles are congruent.
Not necessarily. Let's say that there is a circle with the area of 10. Now there is a star with the area of 10. They do not have the same perimeter, do they? That still applies with rectangles. There might be a very long skinny rectangle and a square next to each other with the same area, but that does not mean that they have the same perimeter. Now if the rectangles are congruent then yes.
No
They need not be congruent so the question is based on a fallacy.
if you mean congruent as allowing to rotate, reflect then yes 1 likely though
No, only those rectangles that are squares have four congruent sides.
Six rectangles. Three pairs of congruent rectangles. Imagine a standard box unfolded. The two ends are the same, the sides are the same and the top and bottom are the same.
Yes, into infinitely many sets of congruent rectangles. In fact, all plane shapes - including totally random ones - can be divided into sets of congruent shapes.
Only if they are congruent. One of them could be the a rotation of the other - eg 4m x 6m and 6m x 4m.
area = 144 square units perimeter = 48 units
because that is how rectangles are defined. that's like asking why are all circles round-_-;;because the opposite sides are congruent (same).
No, rectangles do not have congruent sides. Squares have congruent sides.
