Question 1106520
<br>
It is called a quadrilateral....<br>
We know one angle of the quadrilateral is 90 degrees, because the diagonals of the kite are perpendicular to each other.  We also know another angle of the quadrilateral is 60 degrees, because it is an angle of the equilateral triangle.<br>
But we don't know anything about the other two angles; so there is no special name for the quadrilateral.
