Only if it is an isosceles trapezoid otherwise no.
If you mean on opposite sides yes. There are 2 pairs of congruent angles.
Yes.
If the trapezoid is an isosceles trapezoid, with congruent legs, then the base angles are congruent. Otherwise, no.
Yes. The lower base angles are congruent. The upper base angles are congruent.
By definition, all trapezoids must have one pair of parallel sides. Therefore, an isosceles has one pair of congruent angles.
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
No but the base angles are congruent
There are two pairs of congruent base angles in an isosceles trapezoid.
