What's another name for an equilateral quadrilateral?
Equilateral quadrilateral is a rhombus.
Rhombus is usually defined as an equilateral parallelogram. Since it's given that our quadrilateral is equilateral, all we have to prove is that it's a parallelogram.
As a general theory of quadrilaterals refer to Unizor under menu items Geometry - Quadrangles (quadrangles and quadrilaterals are equivalent terms, one refers to four angles, another - to four sides).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- A quadrilateral has sides of lengths 3cm,4cm,5cm and 'x' cm. What is the greatest possible integral value of 'x'?
- A parallelogram has sides with lengths of #15 # and #8 #. If the parallelogram's area is #8 #, what is the length of its longest diagonal?
- The coordinates of the vertices of a parallelogram ABCD are A(0,0) B(b,y), C(a+b,y) and D(a,0). If ABCD is a rhombus, how would you express y in terms of a and b?
- Given A(1, 1), B(0,5), C(4,4), and D(5, 0). Use the fact that if the diagonals of a parallelogram are perpendicular, then it is a rhombus to prove ABCD is a rhombus?
- A parallelogram has sides with lengths of #16 # and #9 #. If the parallelogram's area is #96 #, what is the length of its longest diagonal?
