Use your understanding of congruence to explain why a triangle cannot be congruent to a quadrilateral. a. why can’t a triangle be congruent to a quadrilateral? b. why can’t an isosceles triangle be congruent to a triangle that is not isosceles?

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

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
