There are numeroud relations between kites and isosceles trapezoids.
For instance, take a kite KITE with KI=IT and TE=EK (it is ok to have IT=TE, a rhombus being a special kite) Construct the diagonals (lines) IE and KT and intersect them at D (I suggest the name diacenter for this point for all quadrilaterals). Construct the four circles which each contain two vertices of the kite and the diacenter. The centers of these four circles form an isosceles trapezoid (except for those who exclude the rectangle as being an isos. trap. in certain cases.)
