Quadrilaterals are more commonly seen in the surroundings than triangles.Most objects around us like doors, windows, tables, notebooks, televisions, and phones are shaped like rectangles or squares. These shapes are easier to use, build, and arrange, which is why they are everywhere—in homes, schools, and public places.While triangles can be seen too, like in roof designs or warning signs, quadrilaterals appear more often because they are more practical and useful in daily life.
