Chapter 9, Problem 7PT

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 does not mapped onto itself by the reflection in the plane and does not mapped onto itself by rotation between $0°$ to $360°$ , so the given figure neither has plane symmetry nor has the axis symmetry.

Thus, the given figure neither has plane symmetry nor has the axis symmetry.
