<span>Triangles can only congruent if all its corresponding sides and angles are congruent. Therefore, two triangles in which only one of them is isosceles cannot be congruent because an isosceles triangle has two equal sides and a non isosceles triangle does not have this property therefore one or two corresponding sides cannot be congruent. an exception to this is if the two said triangles are both equilateral then they can be congruent because an equilateral is considered isosceles.
