Answer:
congruency means that the size and shape must be exactly the same in the figures that are compared. A triangle cannot be congruent to a quadrilateral because it has three sides whereas a quadrilateral has four. An isosceles triangle cannot be congruent to a non isosceles triangle because the sides would be different lengths.
Step-by-step explanation:
hope this helps :)
A triangle be congruent to a quadrilateral because congruent shapes have the same sides and angles. If the number of sides/angles is not even the same, how can the two sets be the same?
An isosceles triangle be congruent to a triangle that is not isosceles because an isosceles triangle has two sides with equal length. If a triangle is not isosceles, all its side lengths are different, so the three sides can't have the same length
