The diagram shows the universal set U = {parallelograms}. Set A represents parallelograms with four congruent sides, while Set B represents parallelograms with four congruent angles. How many of the parallelograms fall into the category A B?

Respuesta :

Answer:

U  ={ Parallelograms}

A= { Parallelogram with four congruent sides}={ Rhombus,Square}

B ={ Parallelograms with four congruent angles} ={ Rectangle, Square}

So, AB= { Square}

So among all the parallelograms "Square" is the only parallelogram which has all congruent sides as well as all congruent angles.
