Reflection Realities
This line acts as a mirror; the preimage and image are exactly the same distance from it.
Line of Reflection
A translation is most commonly referred to by this five-letter word, indicating a smooth movement without turning.
Slide
This is the mathematical term for the original figure before any transformation has taken place.
Preimage
If the rule is (x+2, y), a point will slide 2 units in this direction.
Right
You are performing this transformation when you push a hockey puck straight across an ice rink.
Translation
In a reflection, the preimage and image have the same size and shape, but they differ in this specific characteristic.
Orientation
In a translation, every single point of a figure must move the exact same distance and in the exact same one of these.
Direction
This is the mathematical term for the new figure produced after a transformation has occurred.
Image
Moving a figure 4 units left and 5 units up is represented by this mathematical coordinate rule.
(x-4, y+5)
You are witnessing this transformation when you look at a mountain range mirrored in a completely still lake.
Reflection
If you reflect a right-handed glove across a line of reflection, the image will look like a glove for this hand.
Left hand
If you translate the point (1, 1) using the rule (x + 2, y - 3), you will end up at this coordinate point.
(3, -2)
This small apostrophe-like mark is added to a letter (like A becoming A') to identify it as the transformed point.
Prime notation
If a point is located at (3, 4) and reflects across the x-axis, this is its new coordinate location.
(3, -4)
If a triangle pointing up is transformed and now points down, but hasn't been rotated, it underwent this transformation.
Reflection
If the point (4, 5) is reflected over the horizontal line y = 1, these are its new coordinates.
(4, -3)
If you slide a triangle up and to the right, the lengths of the sides and the measures of the angles undergo this change.
No change
A transformation maps points from an input space to an output space. In coordinate geometry, these two axes define that space.
x-axis and y-axis
If a point is located at (-2, 5) and reflects across the y-axis, this is its new coordinate location.
(2,5)
If point A is at (0, 0) and its new image A' is at (-7, 8), this is the specific translation rule that was applied.
(x-7,y+8) 1000 points
7 units left
8 units up
Regular amount of points
The translation rule (x, y - 4) means the figure is shifting 4 units which way.
Down
Applying the translation rule (x - 4, y + 7) to a point at the origin (0,0) will place the new image in this specific quadrant of the coordinate plane.
