TRANSFORMATIONS(CHANGES)

• TRANSLATIONS (SLIDES)
• REFLECTIONS (FLIPS)
• ROTATIONS (TURNS)
• DILATIONS (STRETCHES)

Congruent Figures

• Congruent figures are figures that
• are the same size.
• are the same shape.

7
Transformations

• A transformation is a change. This change can be
  in the figures location or orientation. A
  figures orientation refers to how it is
  arranged.

8
TRANSLATIONSThe sliding of a figure from one
location to another.

• There is no change in shape, only a change in
  location.

9
TRANSLATIONS

• There is no change in shape, only a change in
  location.
• This figure is congruent
• to the original figure.

10
TRANSLATIONS

• There is no change in shape, only a change in
  location.

11
TRANSLATIONS

• There is no change in shape, only a change in
  location.
• This figure is congruent to the original
  figure.

12
REFLECTIONSA mirror image

• The distance between the image and the mirror
  MUST be the same as the distance between the
  mirror and the reflection. These figures are
  congruent.

13
REFLECTIONS

• The distance between the image and the mirror
  MUST be the same as the distance between the
  mirror and the reflection. These figures are
  congruent.

14
REFLECTIONS

• The distance between the image and the mirror
  MUST be the same as the distance between the
  mirror and the reflection. These figures are
  congruent.

15
REFLECTIONS

• The distance between the image and the mirror
  MUST be the same as the distance between the
  mirror and the reflection. These figures are
  congruent.

16
ROTATIONSTurns

• A rotation of 90 degrees clockwise

17
ROTATIONS

• A rotation of 90 degrees clockwise
• This figure is congruent to the original figure.

18
ROTATIONS

• A rotation of 90 degrees counterclockwise

19
ROTATIONS

• A rotation of 90 degrees counterclockwise
• This figure is congruent to the original figure.

20
ROTATIONS

• A rotation of 180 degrees clockwise

21
ROTATIONS

• A rotation of 180 degrees clockwise
• This figure is congruent to the original figure.

22
ROTATIONS

• A rotation of 180 degrees counterclockwise

23
ROTATIONS

• A rotation of 180 degrees counterclockwise
• This figure is congruent to the original figure.

24
ROTATIONS

• A rotation of 360 degrees clockwise

25
ROTATIONS

• A rotation of 360 degrees clockwise
• This figure is congruent to the original figure.

26
ROTATIONS

• A rotation of 360 degrees counterclockwise

27
ROTATIONS

• A rotation of 360 degrees counterclockwise
• This figure is congruent to the original figure.

28
Dilations

• A dilation is a stretch.

29
Dilations

• A dilation is a stretch.
• This figure is NOT congruent to the original
  figure.

30
Dilations

• A dilation is a stretch.

31
Dilations

• A dilation is a stretch.
• This figure is NOT congruent to the original
  figure.

32
True or False?

• When a shape is translated, the shape is flipped
  over a line creating a mirror image?

33
FALSE!

• When a shape is translated, it is simply moved to
  another location. The orientation, form, and
  size of the shape remain unchanged.

34
True or False?

• A rotation is a turn in either the clockwise or
  counterclockwise direction.

35
True!

• The turn of a rotation can be in either
  direction clockwise or counterclockwise.

36
True or False?

• If a shape is rotated 360 degrees, it ends up in
  the same position that it started.

37
True!

• The shape rotates in a complete circle.

38
True or False?

• It is possible for a reflected image to be
  located 5 feet from the mirror while the image
  itself is located 10 feet from the mirror.

39
False!

• The distance between the image and the mirror,
  and the reflection and the mirror must be the
  same.

40
True of False?

• A dilated figure is congruent to its original
  figure.

41
False!

• Stretching changes the size of the figure.
