I'm fairly certain that this cannot be done.
Divide the longer edge (or shorter one, for that matter) by 5, mark the 4 spots along the edge going by the answer of your division, and there you have it.
Its diagonals divides it into two equal right angle triangles.
Select any one side and divide its length into 5 equal parts. Draw lines that are parallel to the adjacent side to the opposite side. This will divide the rectangle into 5 equal strips.
prove any two adjacent triangles as congruent
You put 3 triangles in it.

Its diagonals divides it into two equal right angle triangles.
Yes, two equal right-angle triangles.
Impossible
Divide it into equal parts with horizontal or vertical lines.
Might be divide it to rectangle
You divide it into parts of 1.2by4
Select any one side and divide its length into 5 equal parts. Draw lines that are parallel to the adjacent side to the opposite side. This will divide the rectangle into 5 equal strips.
prove any two adjacent triangles as congruent
Yes if it's divided diagonally.
have have to divide them
Yes.
