Regular polygons have as many lines of symmetry as sides. An equilateral triangle has 3, a square has 4, a regular pentagon has 5, a regular hexagon has 6, and so on, up to the n-gon. Class 6 NCERT Ganita Prakash ...
Yes, the building has rotational symmetry around its center. The angles of rotational symmetry would likely be 90°, 180°, 270°, and 360°, as the building has symmetrical sections that repeat at these intervals. Class 6 NCERT Ganita Prakash Chapter 9 Symmetry class ...
Yes, the outer boundary of the new Parliament Building has reflection symmetry. Multiple lines of symmetry can divide it, passing through its central axis, ensuring identical mirrored halves on either side. Class 6 NCERT Ganita Prakash Chapter 9 Symmetry class 6 Mathematics ...
No, a figure cannot have a smallest angle of symmetry of 17° because 17° is not a divisor of 360°. For rotational symmetry, the angle must divide 360° evenly. Class 6 NCERT Ganita Prakash Chapter 9 Symmetry class 6 Mathematics Textbook Chapter ...
