If the trapezoid is an isosceles trapezoid, with congruent legs, then the base angles are congruent. Otherwise, no.
An isosceles trapezoid
A trapezoid can be proven isosceles by proving that the 2 legs are congruent (by definition), or that the 2 base angles (either upper or lower) are congruent.
No, an isosceles trapezoid does not have four congruent sides. An isosceles trapezoid has a pair of parallel sides (the bases) and the non-parallel sides (the legs) are of equal length, but the lengths of the bases are generally different. Thus, it has only two pairs of congruent sides, not four.
