It is a rhombus.
In an isosceles trapezoid, the non-parallel sides (the legs) are congruent, but the consecutive sides (one leg and one base) are not necessarily congruent. The two bases (the parallel sides) are also not equal unless the trapezoid is a rectangle. Thus, while the legs of an isosceles trapezoid are congruent, the consecutive sides are not.
a rhombus
