2 If the rectangle has equal sides (ie it's a square) the order is 4.
180 degrees
Join the mid points of a pair of opposite sides of a rectangle. Rotate the rectangle using this line as the axis for rotation, and it will mark out a cylinder..
If you mean "Does it have a rotational symmetry", the answer is "Yes." there is a 180 degree rotational symmetry.
order of rotation of semicircle is 1. angle of rotation of semicircle is 360 degree. If you want to find angle of rotation of a shape, then divide 360 from order of rotation of a shape.
4
I think it would be 1 because the question says ROTATIONAL ORDER and, of course, that would have something to do with rotation. I think it would be 1 because you can rotate a rectangle once but if you rotate it again it will just turn into the rectangle it was before.
Rotational symmetry of order 2. Reflection symmetry about the perpendicular bisectors of the sides.
centre it and that is the answer
180 degrees
180 degrees
It must be. A cylinder is described by the volume swept by a rectangle in rotation about one of its axes. The rotation will create a circle on the opposite ends.

A rectangle has rotational symmetry of order 2. This means it can be rotated 180 degrees around its center and still look the same, as well as being symmetrical at 0 degrees (the original position). However, it does not have symmetry at 90 or 270 degrees, unlike a square, which has rotational symmetry of order 4.
A parallelogram, other than a rhombus or rectangle.
order of rotation of a semi circle is 1
If you mean "Does it have a rotational symmetry", the answer is "Yes." there is a 180 degree rotational symmetry.
It has rotational symmetry of degree 2 or, if it happens to be a square, of degree 4.
