Inequality Form:
−3 < x < 1
Ответ:
If this figure is symmetric (as it seems to be) then is invariant to rotations of 90° in the plane where the center of each segment coincides with an axis, and when the axis of rotation is on the center of the figure.
So the rotation of 0°, the rotation of 90° and the rotation of 180° are possible solutions.
Here 180° because if you rotate the figure by 90° two times, you get 180°.
