Any polygon with more than 4 sides.
A quadrilateral has two and only two diagonals. That's the maximum and also the minimum. If it has more or fewer than two diagonals, it's not a quadrilateral.
Most shapes will have more than two sides. If the sides are straight lines, the shapes MUST have more than two sides.
Hexagon
A decagon and any polygon above a pentagon has more than two lines of symmetry
Not all quadrilaterals with perpendicular diagonals are kites, but all kites have perpendicular diagonals. A kite is defined as a quadrilateral with two pairs of adjacent sides that are equal in length. While other quadrilaterals, such as certain types of rhombuses or irregular shapes, can also have perpendicular diagonals, they do not necessarily meet the criteria to be classified as kites.

true
A 3-gone does not have diagonals. The two diagonals of a 4-gon meet at a point. For all values greater than 4, the diagonals of an n-gon need not necessarily meet at a single point.
It has two diagonals
A parallelogram has two diagonals
Yes. For example, dodecagons, squares and triangles.
THey are plane shapes bounded by two pairs of parallel lines which meet, pairwise, at four right angles. The two diagonals are of equal length and they bisect one another.
two diagonals and with symetric center of two diagonals
There are two diagonals in a trapezoid.
