To construct a rhombus given the measure of its two diagonals, which property of the rhombus do we use?
Diagonals bisect each other at 90∘
In order to construct a rhombus given its diagonals, we need to know the point of intersection of the diagonals and the angle between the diagonals.
As no other information is provided, we will use the diagonals of a rhombus bisect each other at 90∘
Hence (c)
