Hello, blame_canada100!

Al says: "If <a <b <c <d is a parallelogram, then ABCD is a rhombus".

Sketch a quadrillateral ABCD that shows that Al's statement is __not__ always true.

The sketch must show the length of each side & the measure of each angle

of the quadrilateral you draw. Explain.

A rhombus has four equal sides.

We have parallelogram $\displaystyle ABCD$ Code:

A 8 B
* - - - - - - - *
/ 120° 60°/
3 / / 3
/60* 120*/
* - - - - - - - *
D 8 C

but it does __not__ have four equal sides.

It is not a rhombus. .Al is wrong . . .
