Given only a line segment there are numerous steps that need to be taken to construct a diamond. Recall a diamond is a parallelogram with four equilateral sides where the diagonals are vertical and horizontal.

The first step in constructing a diamond would be to calculate the length of the line segment ${\displaystyle \stackrel{¯<!--\; ¯\; -->}{}AB}$. After the length is known then the slope can be found and from there, each of the connecting lines can be drawn.
Therefore, the correct answer is,

"Calculate the length of ${\displaystyle \stackrel{¯<!--\; ¯\; -->}{AB}}$
