Exploring Line and Rotational Symmetry
A figure has line symmetry if a fold maps it onto itself, and rotational symmetry if a turn of less than a full circle does. A regular polygon has both, with as many lines of symmetry as it has sides. Reflective Symmetry (Line Symmetry): A figure has line symmetry if there’s a line (called the […]
Identify Lines of Symmetry
Identify Lines of Symmetry, Example 2: This line is not a line of symmetry because it can’t be used to divide the shape into equal halves.
