The statement that best describes Lucia's claim is at option (b), that is " Lucia's claim is incorrect since not all the rotations that are multiples of 45° carry a square onto itself".
What is the rotational symmetry of a square?
- Two halves of the square when a mirror line is drawn resemble the same or similar, then that square is said to be in symmetry.
- When the square is rotated about an angle, then it remained the same as the original shape, then that square is said to be the rotational symmetry of a square.
Rotation of the given square and its symmetry according to the rotation:
It is given that, Lucia draws a square and plots the center of the square.
Lucia claims that " any rotation about the center of the square that is a multiple of 45° will carry the square onto itself".
To verify this claim, we need to construct a square (ABCD) as shown in the figure.
When the square ABCD is rotated about 45° where we can it is 1 × 45°, the square formed is A'B'C'D' is not the same as the actual one. So, they are not in symmetry after the rotation n this case.
If we rotate again, that is for the second multiple of 45° (2 × 45°), we get a square A''B''C''D''. But, now the square is similar to the actual one. So, they are in symmetry.
This means we can say that, not for all the multiples of 45° rotation, the square does not carry onto itself.
Therefore, we can conclude that "Lucia's claim is incorrect since not all rotations that are multiples of 45' carry a square onto itself".
