Jasper Macdonald · Answer 1

Answer: C. Sammy can use the slope formula to show that the opposite sides have equal slopes

Step-by-step explanation: This is the only option that makes sense. If you think about it, a rhombus has two pairs of parallel sides and 4 congruent sides. If you were to use the distance formula to find out that all sides are congruent, then it might mislead you into thinking it was a square. However, if you use the slope formula to find that that opposites sides have equal slopes and are parallel. This is something that applies to a rhombus and not a square. Therefore, answer C. is the correct choice.

Sammy can use the distance formula to show that all sides are equal.

Step-by-step explanation:

Sammy can use the distance formula to show that all sides are equal. A rhombus has 4 congruent sides, so finding the distance of all the sides and determining that they are all equal would make a rhombus.
