Use the Orbit Stabilizer Theorem to deduce the number of elements in the rotational symmetry group of the cube. I can write Stab G ( v) = { g ∈ G ∣ g ⋅ v = v } and Orb G ( v) = { g ⋅ v ∣ g ∈ G } The orbit has size 8. Is it enough to say that it is 8 simply because there exists a symmetry such that a specific ...

How many planes of symmetry does a cuboid have? - Answers
WebThe blue lines above show just one way to divide the pentagon into triangles; there are others. The sum of the interior angles of the three triangles equals the sum of interior angles of the pentagon. Since the sum of the interior angles of a triangle is 180°, the sum of the interior angles of the pentagon is 3 × 180° = 540°. Regular pentagon WebMay 10, 2024 · An axis of symmetry can only passes through (1) mid-points of two opposite edges. (As a cube has 12 edges, there are $12\div2=6$ axes of this type.) (2) two opposite vertices. (As a cube has 8 vertices, there are $8\div2=4$ axes of this type.) (3) the centres of two opposite faces. (As a cube has 6 faces, there are $6\div2=3$ axes of this type.) Web90° + 90°= 180° i.e. equal to 180°. Hence, (a) is the correct option. Question 3: The number of lines of symmetry in the figure given below is. (a) 4 (b) 8 (c) 6 (d) infinitely many. Solution: (c) given figure has 6 lines of … dewitt stern group inc. zoominfo
