Johnny is wanting to prove that parallelogram ABCD is a rectangle. He shows that opposite sides are congruent and opposite parallel. Can he conclude ABCD is a rectangle ? Why or why not. Explain your reasoning in complete sentences.

No, because the statement explains a parallelogram also.

Step-by-step explanation:

A rectangle is a quadrilateral that has four sides which has a set of equal opposite sides that are parallel to each other. The sum of all angles in a rectangle =

No, he can not conclude that ABCD is a rectangle with the statement because the statement is applicable to a parallelogram also. He could add that opposite sides are straight and parallel. So that:

<ABC = CDA = (right angle property)

<DAB = <BCD = (right angle property)

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

i think the answer is d im not sure
