the line of symmetry from the middle
A triangle can be rotated through any angle of your choice!An equilateral triangle has rotational symmetry of order 3, which means that a rotation of 120 degrees (or multiples) will bring it back to the same orientation. All other triangles have rotational symmetry of order 1: that is, you have to rotate them a full circle (360 deg) before they look the same.
A decagon has 10 sides, so it also has 10 angles. Each angle of a decagon is 36 degrees (360 degrees divided by 10). Therefore, a decagon has 10 angles of rotation symmetry.
Well, isn't that just a happy little question! When we talk about the angle of rotation of alphabets, we're looking at how much they have turned from their original position. It's like giving each letter a little spin to create a fun and artistic effect. Just remember, there's no mistakes here, only happy accidents!
No, that is false since the question describes rotational symmetry. A reflection of a shape on the Cartesian plane produces a mirror image. A rotation of a shape on the Cartesian plane turns the shape through an angle at a fixed point.
The square has 4 sides and has rotational symmetry of order 4. Also, the angle rotation measurement is 90 degrees.
To find the smallest angle of rotational symmetry for a figure, divide 360 degrees by the number of rotational symmetries of the figure. The result will give you the smallest angle of rotational symmetry.
None. You can rotate a circle by the smallest possible angle that you can think of and it will be an angle of symmetry. And then you can halve that angle of rotation and still have rotational symmetry. And you can halve that angle ...
Sometimes called rotation symmetry, or symmetry of rotation. If you have an object that can be turned through a certain angle (like rotating a cube through 90o) and then it looks identical, then that object has a certain symmetry under rotation. If you can turn it through any angle, like a cylinder, then it has rotation (or rotational) symmetry.
A "pure" trapezoid (a pair of parallel sides and two random sides) does not have rotational symmetry. If it is a parallelogram then it has a 180 degree symmetry. And if the paralloelogram happens to be a square, you have 90 deg symmetry.
Yes, because if a regular polygon is turned around a specific point (the angle of rotation) and matches up again, it has rotation symmetry. For example, a hexagon is a regular polygon with six sides. All sides are the same length and the same size. When you turn it around the angle of rotation, it matches with the next side. Therefore, all regular polygons have rotational symmetry. Hope this helps!
It is the axis of symmetry which is a line such that a object that is rotated at right angles to it becomes congruent to its original state before the angle of rotation reaches 360 degrees.

No, a parallelogram does not have rotational symmetry because it cannot be rotated onto itself. Rotational symmetry requires an object to look the same after being rotated by a certain angle.
