Ex.14.3 Q3 Symmetry - NCERT Maths Class 7
If a figure has two or more lines of symmetry, should it have rotational symmetry of order more than \(1\)?
What is unknown?
The figures have rotational symmetry of order more than \(1\).
Rotational symmetry is when an object is rotated around a center point (turned) a number of degrees and the object appears the same. The order of symmetry is the number of positions the object looks the same in a \(360^\circ\) rotation.
Yes, because every line through the centre forms a line of symmetry and it has rotational symmetry around the centre for every angle.
