Can we have a figure with rotational symmetry whose smallest angle of symmetry is 45°?

  • 2

No, a figure cannot have a smallest angle of symmetry of 45° because 45° is not a divisor of 360°. For rotational symmetry, the angle must divide 360° evenly.

  1. A figure cannot have a smallest angle of symmetry of 45° because 45° is not a divisor of 360°. For rotational symmetry, the smallest angle of symmetry must divide 360° evenly. In cases where the smallest angle is 45°, there would be no symmetry at specific intervals. For example, regular shapes like squares, triangles, or hexagons have rotational symmetry where the angles are divisors of 360° (such as 90°, 60°, etc.).
