The base angles of an isosceles trapezoid are congruent
They can be as for example in an isosceles trapezoid.
By definition, all trapezoids must have one pair of parallel sides. Therefore, an isosceles has one pair of congruent angles.
They are congruent angles.
An isosceles trapezoid
The base angles are congruent in an isosceles trapezoid
The base angles of an isosceles trapezoid are congruent
There are two pairs of congruent base angles in an isosceles trapezoid.
If the trapezoid is an isosceles trapezoid, with congruent legs, then the base angles are congruent. Otherwise, no.

No but the base angles are congruent
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.

Yes, an isosceles trapezoid has one pair of congruent opposite sides and congruent base angles
By definition, all trapezoids must have one pair of parallel sides. Therefore, an isosceles has one pair of congruent angles.
