By definition, all trapezoids must have one pair of parallel sides. Therefore, an isosceles has one pair of congruent angles.
Normally none unless it is an isosceles trapezoid then it will have 2 equal end sides of the same lengths
A trapezoid may have zero or one pair of congruent sides.
A trapezoid normally has no congruent sides
An isosceles triangle has exactly two sides which are equal. (The word congruent usually applies to triangles, not sides.)
What kind of isosceles? A isosceles triangle has 3 sides, while a isosceles trapezoid has 4 sides. Hope i helped:)
