Symmetry review
CCSS Math: 4.G.A.3
Review symmetrical shapes and lines of symmetry. Then, try some practice problems.
Line of symmetry
A is a line where we can fold the image and have both halves match exactly.
Example:
When we divide the figure with Line , the resulting two parts are mirror images of each other:
Line is a line of symmetry.

Symmetrical figures
Shapes are if they have at least one on them.
Example:
This shape is :
Because we can draw at least one on it:
