So, a regular pentagon has rotational symmetry of order 5. You only need to rotate the figure up to 360 degrees. Order of rotational symmetry.
Ask your question. At which angle of rotational symmetry will triangle ABC map onto itself? Log in.
~LoveYourselfFirst:) You cannot have a shape or object that has an order of 1. It equals 360 degrees . - 3572381 1. Once you have rotated the figure 360 degrees, you are back to the original figure. The result looks exactly like the original rectangle. Log in. Mathematics. High School. A shape has rotational symmetry when it can be rotated and it still looks the same. 5 points kahleelflournory Asked 04/27/2017. Another way to say this is that the figure has n-fold rotational symmetry. ☆ Basically angle of "rotational symmetry" or "rotation symmetry" is an object with the same show after it was being rotated during the turning process. The images B and C are generated by rotating the original image A. Solution : Please look at the images of the parallelogram in the order A, B and C. A is the original image. Join now. The order of rotational symmetry of a geometric figure is the number of times you can rotate the geometric figure so that it looks exactly the same as the original figure. At which angle of rotational symmetry will triangle ABC map onto itself? A rectangle can be rotated about its centre by half a turn. Example 4 : What is the order of rotational-symmetry of a parallelogram ? Rotational symmetry. The smallest order would be an order of 2. Rotational symmetry Rotational symmetry of a rectangle. 1. Join now. Instead, we will almost always use the order of rotation to describe rotational symmetry: Order of rotation : A figure has order n rotational symmetry if 1/n of a complete turn leaves the figure unchanged. Thus your answer is: 360 degrees (Option D) Good luck on your assignment and enjoy your day! Rotational symmetry with 120 degrees rotation This one has an order of 3.
