1. GEOMETRY SLIDESHOW 2:

2. CONGRUENT Figures are the same SIZE and SHAPE
NOT Congruent
NOT Congruent
not same size
not same shape

3. Which figures are congruent?

4. A and G D and I E and J C and H
Did you get the following pairs?
A and G
D and I
E and J
C and H
Remember: Shapes can be congruent even if one of them
has been rotated (as in A and G) or reflected (as in C and H).

5. SIMILAR Figures have the same shape, but not size.

6. SIMILAR Figures have the same shape, but not size.

7. MOTIONS: There are 3 different ways to move a plane figure:
*SLIDE *FLIP *TURN

8. *SLIDE – Translation *FLIP – Reflection *TURN - Rotation

9. SLIDE: TRANSLATION
Moves a figure in a straight direction

10. FLIP: REFLECTION
gives a mirror image of a figure

11. TURN: ROTATION
moves a figure about a point

12. A slide or translation…

13. A slide or translation…
moves a figure in a straight direction L L

14. A flip or reflection…

15. A flip or reflection…
gives a figure its mirror image L L

16. A turn or rotation…

17. A turn or rotation…
moves a figure about a point L L

18. SYMMETRY A rectangle is a symmetric figure because it can be folded into 2 congruent halves that fit on top of each other. Each of your folds lie along a line of symmetry. The rectangle has two lines of symmetry.

19. SYMMETRY This W has only one line of symmetry.
