symmetriapistettä

Symmetriapistettä refers to a point of symmetry in geometry. In a two-dimensional shape, a point of symmetry is a point such that for every point on the shape, there is a corresponding point on the shape such that the line segment connecting these two points is bisected by the point of symmetry. This means that if you rotate the shape 180 degrees around its point of symmetry, the shape will perfectly overlap with its original position. For example, a square has a point of symmetry at its center. A rectangle also possesses a point of symmetry at its center. An equilateral triangle, however, does not have a point of symmetry. In three dimensions, a point of symmetry is defined analogously. A sphere has a point of symmetry at its center. A cube has a point of symmetry at its geometric center. The concept is fundamental in understanding the rotational symmetry of objects.
