In a rhombus, the diagonals are perpendicular bisectors of each other, and they bisect the angles of the rhombus. This means that a rhombus is essentially made up of four congruent right-angled triangles. We can use the Pythagorean theorem to find the length of one side of the rhombus (s) s2=82+62 s2=64+36 s2=100 s = √100 s =10 cm So, the length of each side of the rhombus is 10 cm.
