yes a kite with parallel sides is a rhombus.

"Is a Kite with only one pair of parallel sides still a rhombus?"

A kite cannot have a single pair of parallel sides (a trapezoid). Either no sides are parallel, or it is a rhombus with both sides parallel.

Yup, xyzzy is correct.

Yes !

We flew beach kites, the large ones which required the flyer to be harnessed and tethered down. Otherwise the kite would take you out into the ocean or lake very quickly.

These kites had parallel sides, they were big, and created very high pulling force against the flyer.
