WebThe way that I remember it is that 90 degrees and 270 degrees are basically the opposite of each other. So, (-b, a) is for 90 degrees and (b, -a) is for 270. 180 degrees and 360 degrees are also opposites of each other. 180 degrees is (-a, -b) and 360 is (a, b). 360 degrees doesn't change since it is a full rotation or a full circle.

Formally the rotational symmetry is symmetry with respect to some or all rotations in m-dimensional Euclidean space. Rotations are direct isometries, i.e., isometries preserving orientation. Therefore, a symmetry group of rotational symmetry is a subgroup of E (m) (see Euclidean group). Symmetry with respect to all rotations about all points implies translational symmetry with respect to all translations, so space is homogeneous, and the symmetry group is the whole E(m). With the modified … WebA line of symmetry is a line that you can draw across a shape and divide it into two mirror-images. That is to say, each half of the shape is the same, but looks like its been flipped from the other. You can also think of a line of symmetry as a line that you can draw, that when you fold the shape over the line both edges would line up exactly ...

WebJan 24, 2024 · Ans: A shape is said to have rotational symmetry when it looks the same even after a rotation. Rotation can be clockwise or anti-clockwise. When an object or a shape rotates, its size and shape do not change. Instead, it undergoes a turning movement about a specific point known as the centre of the rotation. WebMay 4, 2016 · A line of symmetry for a triangle must go through one vertex. The two sides meeting at that vertex must be the same length in order for there to be a line of symmetry.
