Mistakes in study.com lessons/quizzes

[acamp]

Hey there,
I was going over one of my practice final exams for the MAT 102 course and I found a mistake in the practice final.  The question reads:

17. A four-sided shape has all right angles and sides of equal length. That means the shape is both a _____
Incorrect
Topic: Geometry
Both of these options are correct
Watch correct answer

square and a rectangle

square and a rhombus

Neither of these options are correct

Study.com says that the correct answer is BOTH OF THESE OPTIONS ARE CORRECT which that isn't true.  A rhombus does NOT 4 right angles. I just confirmed this with TWO math teachers =)

A rhombus CAN have 4 right angles (a square is a rhombus), but it doesn't necessarily have 4 right angles.  So the question is not a good one, even if the answer COULD be correct.

I think with math questions, the answer has to be exactly, 100% correct.  There can't be ambiguity.

But technically, a square and a rhombus is the correct answer.

I appreciate all the responses.  But, a square ALWAYS has 4 right angles.  A rhombus doesn't necessarily have to have 4 right angles.  Usually, a rhombus does not have 4 right angles.  So I agree with you dfrecore - this question is not credible and wayyyyy too ambiguous.    I asked to high school state-certified math teachers and they both said a rhombus doesn't always have 4 right angles and thought the question wasn't a good one..
