A rhombus can be uniquely constructed if only its two diagonals are given because—

athe diagonals bisect each other at right angles
ball sides are unequal
cit is the same as a square
donly its perimeter is needed

ব্যাখ্যা

In a rhombus the diagonals bisect each other at right angles, so the two half-diagonals form four congruent right triangles. The two diagonal lengths therefore locate all four vertices uniquely.
