Translations
A translation moves a figure without changing its ________
shape or size
A rotation moves a figure without changing its __________.
shape or size
True or False: A reflection changes the size of a figure.
false
A dilation that makes a figure larger is called a __________.
enlargement
A reflection over the y-axis changes (x, y) into this.
(-x, y)
In the translation rule (x, y) → (x + 4, y - 2), how does the figure move
4 units right and 2 units down
What direction is a 90° clockwise rotation?
One turn to the right
A reflection in math is similar to looking at your face in this object.
mirror
True or False: A dilation always produces a similar figure.
true
The rule for dilating a point (x, y) by a scale factor of k is what?
(kx, ky)
What is the difference between a translation and a reflection?
translation moves a figure without flipping, while a reflection creates a mirror image
True or False: A rotated figure always looks exactly the same.
False
Reflect (3,5) over the x-axis.
(3,-5)
The ratio used to determine how much a figure is enlarged or reduced is called the __________.
scale factor
If a point (x, y) is translated 3 units right and 4 units up, what is the new coordinate?
(x+3, y+4)
A drone flies 4 meters east and 2 meters south. What transformation does this represent?
(x, y) → (x + 4, y - 2)
What happens to a point (x, y) when rotated 180° counterclockwise about the origin?
(-x, -y)
What happens to the orientation (order of points) of a figure after a reflection?
reversed (flipped)
A dilation with a scale factor between 0 and 1 results in this type of transformation.
reduction
A 180° rotation follows what rule?
(-x, -y)
The ordered pair (4, -6) is translated 6 units right and 2 units up. What is the new ordered pair?
(10, -4)
Rotate (4,-1) 90° counterclockwise about the origin.
What is the new point?
(-1,4)
Reflect (-2,7) over the y-axis.
(2,7)
A point (3,4) is dilated by a scale factor of 2. What are the new coordinates?
(6,8)
What would happen to a shape if I dilated it by a factor of 0.5?
It would get smaller / it would be half the size.
