Diagonals of a rhombus
The diagonals of a rhombus bisect each other at right angles (90°).
Drag the orange dots on each vertex
to reshape the rhombus. Notice the behavior of the two diagonals.
the diagonals (lines linking opposite corners)
bisect each other at right angles (90°).
That is, each diagonal cuts the other into two equal parts, and the angle where they cross is always 90 degrees.
In the figure above drag any
to reshape the rhombus and convince your self this is so.
The area of a rhombus can be found as half the product of the two diagonal lengths. For more on this see
Area of a rhombus.
