The diagram shows the universal set u = {parallelograms}. set a represents parallelograms with four congruent angles . how many of the parallelograms fall into the category a u b?

 The number of parallelograms that fall into the category A ∪ B is 26.

Step-by-step explanation:  The given diagram shows the universal set U defined by

U = {parallelograms}.

Set A represents parallelograms with congruent sides and set B represents parallelograms with four congruent angles.

We are to find the number of parallelograms that fall into the category A ∪ B.

From the diagram, we find that

From set theory, we have

Thus, the number of parallelograms that fall into the category A ∪ B is 26.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
