Answer:
a <em>kite</em> or a <em>square</em>
Step-by-step explanation:
The fact that the diagonals are congruent is irrelevant, unless you also know something about where they cross each other.
A <em>kite</em> has perpendicular diagonals. If they happen to bisect each other, then the result is a <em>rhombus</em>. If the diagonals are congruent, then that rhombus is a <em>square</em>.
<em>Other ways to get there</em>
A pair of congruent diagonals that cross each other symmetrically will define a trapezoid. If they also bisect each other, the result is a rectangle. If the diagonals of that rectangle are perpendicular, then it is a <em>square</em>.
