Respuesta :

since it said all the angles are 90 degrees, it could be either a square or a rectangle, then it specified that the opposite sides only are congruent, which defines a rectangle, unlike a square which has all sides equal.

Answer:

Option C - rectangle

Step-by-step explanation:

"A quadrilateral with opposite sides congruent"  -  This simply means that a four sided shape that has opposite sides that are equal .

This is enough to tell us that is a rectangle but the last part of the statement  only confirms our answer as rectangles are the only shape with all angles as 90.

Hope this helped and have a good day
