False
A reflection is when a figure slides either left or right and up or down.
|
(4, -3)
The point (4,3) becomes...
|
(-4, 3)
The point (4,3) becomes...
|
A line that acts as a mirror so that corresponding points are the same distance from the line.
What is a reflection line?
|
A' (-2,3), B' (-1,0) and C' (0,3)
The points for triangle ABC are A (2,3), B (1,0), and C (0,3). When reflecting over the y-axis, what will be the new points for A, B, and C?
|
|
True
When using reflection, the pre-image and image have the same size and shape.
|
(2, -2)
The point (2, 2) becomes...
|
(-11, -10)
The point (11, -10) becomes..
|
Vertical
When the reflection line is x = #, what kind of line represents the line of reflection?
|
A' (4,8), B' (4,3), and C' (9,3)
The points for triangle ABC are A (8,4), B (3,4), and C (3, 9). If the reflection line is y = x, what will be the new points for A, B, and C?
|
|
True
The reflection line is the line on the graph that the figure is being reflected over.
|
(11, 10)
The point (11, -10) becomes...
|
(4, -7)
The point (-4, -7) becomes...
|
Horizontal
When the reflection line is y = #, what kind of line represents the line of reflection?
|
A' (-2,4) B' (-2,8) and C' (-6, 6)
The points for triangle ABC are A (-4,2), B (-8,2), and C (-6, 6). If the reflection line is y = -x, what will be the new points for A, B, and C?
|
|
False
When the reflection line is x = #, the line is horizontal.
|
(-4, 7)
The point (-4, -7) becomes...
|
(2,0)
The point (-2, 0) becomes...
|
(x,y) ----> (y,x)
What happens to my points (x,y) when the reflection line is y = x?
|
A' (3,3), B' (-1,3), and C' (1,6)
The points for triangle ABC are A (-1,3), B (3,3), and C (1,6). If the reflection line is x = 1, what will be the new points for A, B, and C?
|
|
True
When reflecting over the x-axis, the x-value stays the same and the y-value changes to its opposite.
|
(-2, 0)
The point (-2,0) becomes...
|
(0, -5)
The point (0,-5) becomes...
|
(x,y) ----> (-y,-x)
What happens to my points (x,y) when the reflection line is y = -x?
|
A' (-1, -1), B' (3, -1), and C' (1,-4)
The points for triangle ABC are A (-1,3), B (3,3), and C (1,6). If the reflection line is y = 1, what will be the new points for A, B, and C?
