Chapter 9, Problem 8PT

To determine

To find: Whether the given figure has plane symmetry, axis symmetry, both, or neither.

Explanation of Solution

Given information:

The given figure is,

  

The three dimensional figure is said be plane symmetric if the figure can mapped onto itself by the reflection in the plane and said to be axis symmetric if the figure can mapped onto itself by rotation between $0°$ to $360°$ .

The given figure mapped onto itself by the reflection in the plane and also mapped onto itself by rotation between $0°$ to $360°$ , so the given figure has plane symmetry as well as the axis symmetry.

Thus, the given figure neither has bothsymmetries.
