If pqrs is a rhombus, which statements must be true? check all that apply.

These statements are true:



This is true because of the definition of a rhombus which states that opposite sides are parallel.





This is true because the diagonals of a rhombus bisect each other at right angles.



This is true because the four sides of a rhombus are all equals.



This is also true. Two angles are supplementary when they add up to 180 degrees. Angles in rhombus are equal two to two. Let's name:

 

Then it is true that:



Besides, a rhombus is a quadrilateral and it is true that the interior angles of a quadrilateral add up to 360 degrees, thus:
