1. 1. MathsProject
2. 2. .Symmetry.Rotation.Translation.Reflection
3. 3. Symmetry
4. 4. What is line of symmetry• A line on which a figure can be folded so that both sides match.
5. 5. To be a line of symmetry, theshape must have two halvesthat match exactly.When you trace a heart onto apiece of folded paper,and then cut it out, the two halfhearts make a whole heart.The two halves are symmetrical.
6. 6. Which of these flags have aline of symmetry?United States of America Canada Maryland England
7. 7. What about these math symbols? Do they have symmetry?
8. 8. How many lines of symmetry to these regularpolygons have? Do you see a pattern?
9. 9. Rotation (Turn)• The action of turning a figure around a point or a vertex.
10. 10. Click thetriangle to Turning a figuresee rotation around a point or a vertex
11. 11. Translation (Slide)• The action of sliding a figure in any direction.
12. 12. Click the Octagonto see Translation. The act of sliding a figure in any direction.
13. 13. Reflection (flip) The result of a figure flipped over a line.
14. 14. Click on thistrapezoid toseereflection. The result of a figure flipped over a line.
15. 15. Which shapes show reflection, translation, or rotation?
