Base angles.
The base angels of a trapezoid are the angles that attach to the legs of the trapezoid. There are four base angles in a trapezoid.
The base angles of an isosceles trapezoid are congruent
Sometimes.
A trapezoid may have two right angles.

There are two pairs of congruent base angles in an isosceles trapezoid.

The base angles of an isosceles trapezoid are congruent
If the trapezoid is an isosceles trapezoid, with congruent legs, then the base angles are congruent. Otherwise, no.
A trapezoid always has two acute angles. the base angles have to be acute because the lower base angles and the upper base angles are complementary so since the upper base angle is always obtuse, the lower base angles have to be acute.
'never'
It is a trapezoid in which the non-parallel sides are of the same length and subtend equal angles with the base. It can be viewed as an isosceles triangle whose apex has been removed by a line parallel to its base.
The base angles are congruent in an isosceles trapezoid
The pair of angles at the end of each parallel side - the two base angles and the two top angles - are congruent.
