WebDec 23, 2024 · A parallelogram has rotational symmetry of order two, a 180 degree angle of rotation, and no lines of symmetry. A parallelogram has rotational symmetry, but it … WebGiven A x⃑ = b⃑ where A = [[1 0 0] [0 1 0] [0 0 1]] (the ℝ³ identity matrix) and x⃑ = [a b c], then you can picture the identity matrix as the basis vectors î, ĵ, and k̂.When you multiply out the matrix, you get b⃑ = aî+bĵ+ck̂.So [a b c] can be thought of as just a scalar multiple of î plus a scalar multiple of ĵ plus a scalar multiple of k̂.

WebAug 21, 2015 · Consider an orthonormal basis ${\{v_1,v_2\}}$ in the plane. Say any object (e.g. a vector, shape etc.) in the plane is defined with respect to this basis - so if we can rotate the basis vectors through the angle $\theta$ anticlockwise, this will transform any such defined objects in the same way.
