Definition
Let $F$ be a plane geometric figure.
Let $\map R F$ be a reflection in an axis of reflection $AB$ which is a symmetry.
Then $AB$ is referred to as an axis of symmetry of $F$.
This article is complete as far as it goes, but it could do with expansion. In particular: need to expand "Axis of Symmetry" to take on board the concept of a 3D axis of rotational symmetry You can help $\mathsf{Pr} \infty \mathsf{fWiki}$ by adding this information. To discuss this page in more detail, feel free to use the talk page. When this work has been completed, you may remove this instance of {{Expand}} from the code.If you would welcome a second opinion as to whether your work is correct, add a call to {{Proofread}} the page. |
