Final Answer:
The table is mostly correct, but the "Center of Rotation" for
Trapezium and
Kite should be filled in as
None, since shapes with no rotational symmetry do not have a center of rotation (or it's undefined). However, strictly speaking, *any* shape has a geometric center point, but in the context of rotational symmetry, if there’s
no rotational symmetry, we say the center of rotation is
not applicable or left blank — and the table correctly leaves those cells empty.
But let’s double-check each row:
1.
Parallelogram: Rotational symmetry of order 2 (rotate 180° → matches itself). Center = intersection of diagonals
✔
2.
Regular Polygon with n sides: Order = n (rotate by 360°/n). Center = intersection of diagonals (also center of circumscribed circle)
✔
3.
Rhombus: A special parallelogram → order 2, center = intersection of diagonals
✔
4.
Circle: Infinite rotational symmetry; any rotation about center works → order = Unlimited, center = center of circle
✔
5.
Trapezium (assuming *general* trapezium, i.e., only one pair of parallel sides, not isosceles): No rotational symmetry → order = None, so center is
not defined → blank is acceptable
✔
6.
Kite (non-rhombus): Typically has reflection symmetry but
no rotational symmetry (unless it’s a rhombus), so order = None, center = blank
✔
So the table as given is correct — no changes needed.
Final Answer:
The table is correct as shown.
