The calculated coordinates of K and L are (s, 0) and (0, -t)
How to determine the coordinates of K and L.
From the question, we have the following parameters that can be used in our computation:
The rhombus
Also, we have the coordinates of vertices M and N
Where:
M = (-s, 0)
N = (0, t)
The diagonals of a rhombus bisect each other
This means that the diagonal vertices are equidistant from the origin
So, we have
K = (s, 0) --- because it is at the other end of M
L = (0, -t) --- because it is at the other end of N
Hence, the coordinates of K and L are (s, 0) and (0, -t)
