1. Geometry
Symmetry
What will we learn today?
• identifying symmetric figures
• determining whether a straight line is
a line of symmetry of a symmetric
figure
• completing a symmetric figure with
respect to a given horizontal/vertical
line of symmetry
3. Symmetric Figures
You can find if a shape has a Line of Symmetry
by folding it.
When the folded part sits perfectly on top
(all edges matching), then the fold line is a
Line of Symmetry.
4. Symmetric Figures
When the folded part sits perfectly on top
(all edges matching), then the fold line is a
Line of Symmetry.
5. Symmetric Figures
Try folding it this way!
When the folded part sits perfectly on top
(all edges matching), then the fold line is a
Line of Symmetry.
6. Symmetric Figures
Try folding it this way!
When the folded part sits perfectly on top
(all edges matching), then the fold line is a
Line of Symmetry.
This is line of symmetry.
