D3h
Its extremum is on its axis of symmetry.
A 5 point star has 5 lines of symmetry.
A line but not a point.
Only if it is in the form of an isosceles trapezoid
yes
To assign a point group to a molecule, you first identify its symmetry elements such as rotation axes, mirror planes, and inversion centers. Then, use those elements to determine the point group using crystallographic tables or software. The resulting point group describes the overall symmetry of the molecule.
Point group D_n is a type of symmetry group in chemistry and crystallography. It has a 2-fold rotational axis with n total symmetry elements, including reflections and rotations. The "D" indicates that there are perpendicular C2 axes in the group.
bilateral symmetry
The point group of CH2Cl2, also known as dichloromethane, is D2h. This molecule has a C2 axis, two perpendicular C2 axes, and two mirror planes.
The octahedral point group is significant in crystallography because it represents a high degree of symmetry in crystals. Crystals with octahedral symmetry have eight-fold rotational symmetry, which affects their physical and chemical properties. This symmetry leads to unique optical, electrical, and mechanical properties in crystals, making them important in various scientific and industrial applications.
It is a line through the point of symmetry. In general it is not an axis of symmetry.
The letters S and N have point symmetry but not line symmetry.
A basketball has an infinite number of lines of symmetry. This is because a basketball is a perfect sphere, and any plane passing through its center will divide it into two equal halves that are symmetrical. Therefore, there are an infinite number of lines of symmetry that can be drawn on a basketball.

False
rectangle
No, a triangle does not have point symmetry. Point symmetry occurs when an object or shape remains the same after being rotated 180 degrees around a central point. In the case of a triangle, it does not have point symmetry because it does not look the same after a 180-degree rotation.
