A rhombus has a side length measuring 7 cm.

Is DC equal to 8 cm?

Let's recall the properties of a rhombus. In a rhombus, all sides are equal to each other, therefore DC cannot be equal to 8 cm.

Additionally, in a rhombus, there are 2 pairs of parallel and equal sides. Since the side parallel to AB is CD, it must be equal to 7 cm.
