It is fairly simple to spot quadrilaterals in everyday life, considering it's any four sided polygon. Anything that has a rectangle, square, rhombus, trapezoid, or kite shape is game. Try finding these shapes around your house, for instance right now I am looking at my wipe-off board, which is rectangle shaped, which is next to my sticky notes, which are square shaped. There is in fact a kite in my room, rather a drawing of one, and my boom box is trapezoid shaped (seriously, it is). There is even a rhombus shaped basket in my room (it's not usually there though, I don't know why it is there now). Go ahead and try it and see what you can find. These geometric shapes might surprise you.
