Any shape with an equal number of sides... Square, hexagon, octagon, decagon... etc.
O
No because 90 degrees and 180, 270 degrees don't work for the trapezoid
If you mean "Does it have a rotational symmetry", the answer is "Yes." there is a 180 degree rotational symmetry.
how many lines of symmetry has an equilateral triangle
Line or reflective symmetry is really a special case of rotational symmetry but from a different viewpoint. In line symmetry imagine a line going north to south on the page. If you rotate an image out of the page around that line through 180 degrees you get a reflection. For rotational symmetry imagine that same line being perpendicular to the page so that you see it as a dot. The image is then rotated around that dot.
I have revised this answer. This question is harder than it looks!The numbers 69, 6009 or 98886, for example, would have rotational symmetry (looks the same when rotated by 180 degrees) but not reflection symmetry.So I think the answer is going to be something like:A number which consists of the digits 6 and 9 plus or minus the digits 0 & 8 AND has the digits in the necessary order to maintain rotational symmetry.
A line has 180 degrees rotational symmetry.
No - a pentagon has 120 degree rotational symmetry.
No, it does not.
Yes; 180 degrees.
yes
Yes, a square has rotational symmetry. It has rotational symmetry of order 4, which means it can be rotated by 90 degrees, 180 degrees, and 270 degrees to coincide with its original position.
Yes.Yes.Yes.Yes.
A two-fold symmetry has a 360 degrees rotation. A three-fold rotational symmetry, on the other hand, has 120 degrees, and on a horizontal axis, a symmetry has 180 degrees.
No because 90 degrees and 180, 270 degrees don't work for the trapezoid
yes it does it has all of the degrees......yes,90 degrees,180 degrees, and 270 degrees
The world flags of Japan, Bangladesh, Israel, Hong Kong and Switzerland have 180 degrees rotational symmetry in them. USER ID_Playa101
it has order two (180 degrees)
