A parallelogram is a shape that has two pairs of parallel sides. This means that the sides are straight lines that never meet, and they run parallel to each other. You can find parallelograms in everyday life, such as the shape of a book, a piece of paper, or a road sign. Parallelograms are also used in geometry and math as a way to measure angles and lengths. They are a very useful shape to know about, and can be found in many different places in our world!
