Symmetry means that you should be able to draw a straight line and have both sides of the line be a reflection of the other (reflection like in a mirror or like if you put a miror at the middle of your face and someone looked in it they would see the other side)
Everyone's face has symmetry. Our ears line up, so does our eyes and nose. Now if someone says no because their wearing a mask then no it doesn't, but a human face has symmetry. Even if you are wearing glasses.
