By definition, all trapezoids must have one pair of parallel sides. Therefore, an isosceles has one pair of congruent angles.

How many acute angles does a isosceles trapezoid have?

An isosceles trapezoid can have either two acute angles or two obtuse angles, depending on its specific dimensions. If the non-parallel sides are longer than the height, the trapezoid will have two acute angles. Conversely, if the non-parallel sides are shorter, it will have two obtuse angles. Therefore, an isosceles trapezoid can have zero, two, or four acute angles, depending on its configuration.
