Symmetry

Question 4 • CA-Common Core Geometry DVHS Sem. 1

Which statement supports the claim that Rachel’s figure has point symmetry?

Answer
A
The figure has rotational symmetry of order 1.
B
The figure does not have any lines of reflection.
C
If the figure is rotated 180° about point P, it will map back onto itself.
D
The vertices of the 6-sided star are all points of symmetry that can be used to map the figure onto itself.

Explanation

A figure has point symmetry if a 180° rotation around a point maps the figure onto itself. Choice C states exactly that the figure maps back onto itself when rotated 180° about point P, so it supports the claim.
