17. 4 equal sides 4 right angles 4 right angles diagonals bisect each diagonals bisect each other at right angles other at right angles diagonals are equal diagonals are equal 4 lines of symmetry opposite sides are parallel opposite sides are parallel opposite sides are parallel

18. rotational symmetry order 4 angles add up to 3600 rotational symmetry order 2 angles add up to 3600 angles add up to 3600 angles add up to 3600 angles add up to 3600 opposite sides are parallel 2 pairs of equal sides opposite sides are equal 2 pairs of equal sides opposite sides are equal and parallel 2 pairs of equal sides
