Yes. It has two lines of symmetry - horizontal and vertical. It also has rotational symmetry.
It depends on the quadrilateral. The max number is 4, but the min is 0.
yes
0 is symmetrical because when something is symmetrical it can be split down the middle and have two symmetrical sides or two sides that look the same. If you draw your ones like a straight line then it could be symmetrical depending on your teacher. If your teacher allows you to make your symmetrical lines going horizontal instead of vertical then 3 would also be symmetrical. F.Y.I if you don't trust a enrichment middle schooler who has learned this recently then don't use this information

Yes. Regular polygons with an odd number of sides are also symmetrical.
It is symmetrical
Look: 0 1 2 3 4 5 6 7 8 9 0 is doubly symmetrical (horizontal and vertical axes) 3 is almost symmetrical about the horizontal axis 8 is almost doubly symmetrical 1 is almost symmetrical, and is truly symmetrical in some sans-serif fonts (but not in all languages: cursive French has a long leading stoke on the left)
