In this video the author shows how to draw a rhombus when given with the values of long diagonal (D) and a short diagonal (d). Now he draws the long diagonal of size D horizontally on a sheet of paper. Now he points the mid point of the line as he explains that the diagonals of a rhombus meet at midpoints. So now he takes the ruler and draws an another line perpendicular to the first line through its marked mid point such that the length of the perpendicular line is d/2 both above and below the main diagonal. Now he joins all the four corners of the lines which results in the final rhombus figure. In this video the author demonstrates how to construct a rhombus given the lengths of its long diagonal and short diagonal.
