No, because then it would be a parallelogram.
Yes, an isosceles trapezoid has one pair of congruent opposite sides and congruent base angles
No. A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel. The opposite angles not congruent.
The only real characteristic of a trapezoid is that one pair of opposite sides is parallel. For an isosceles trapezoid, in addition to one pair of opposite sides being parallel; the legs are congruent; each pair of base angles is congruent; and the diagonals are congruent.

They are congruent angles.
A trapezoid Trapezoid - 2 congruent diagonals that do not bisect each other. No right angles and has 1 pair of opposite parallel sides.

By definition, all trapezoids must have one pair of parallel sides. Therefore, an isosceles has one pair of congruent angles.
A trapezoid.
For the quadrilateral to be a parallelogram, both pairs of opposite angles must be congruent.
