Does a rhombus have opposite angles that are supplementary?

Answer 1

Generally speaking, NO. These angles are equal.
But see the details below.

Let's consider a rhombus #ABCD# with #AB=BC=CD=DA#. Draw diagonal #AC# and consider two triangles this diagonal breaks the rhombus into: #Delta ABC# and #Delta ADC#. Obviously, these triangles are congruent by three sides. Therefore, angles #/_ABC# and #/_ADC# are equal in measure.
Supplemental are angles that sum up to #180^o#. Equal in measure angles can be supplemental only in one case - when they both are #90^o#. Therefore, if our rhombus is a square, opposite angles are supplemental. Otherwise, they are not supplemental because they are equal in measure and not #90^o# each.

Answer 2

Yes, a rhombus does have opposite angles that are supplementary. In other words, the measures of the angles formed by the intersection of the diagonals of a rhombus add up to 180 degrees.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
