A square has sides measuring 5 cm.
Is AB parallel to CD?
Let's think about the different types of lines.
Looking at side AB and side CD, we can see that if we extend both of them, they will never intersect.
Also, according to the properties of a rectangle, each pair of opposite sides are parallel to each other.
Therefore, the answer is correct and indeed AB is parallel to CD.
Yes
Look at the square below:
Is a parallelogram a square?
Opposite sides don't share any vertices! In this square, AB (top) is opposite to CD (bottom), and AC (left) is opposite to BD (right). Adjacent sides share a corner.
By definition, a square has four right angles and equal sides. This geometric structure forces opposite sides to run in exactly the same direction, making them parallel.
The orientation doesn't matter! Whether the square sits normally or is rotated, opposite sides remain parallel because the internal angles stay the same.
Not all quadrilaterals have parallel sides! Only parallelograms (including squares, rectangles, and rhombuses) guarantee that opposite sides are parallel.
No measurements needed! Since we're told it's a square, we automatically know opposite sides are parallel. The 5 cm measurement just tells us the size.
