Math-7 NOTES
What:
transformations (reflections). . .
Why:
. . . so I can perform reflections of figures on the coordinate plane.
What is a Reflection??
A
AI
A reflection is a ____________ .
We will reflect on the coordinate plane over both the x axis and the
___________________________ .
How do we perform a reflection??
1)
Identify the line of reflection, or the line that the figure will ____________
over.
2)
Choose a point on the original figure (pre-image), and count the number
of grid lines that lie between the point and the line of _________________ .
3)
Then, count out the ___________ number of grid lines on the OTHER side
of the line of reflection. This is where the new point will be (the “prime”
point).
(Repeat above process for all points on figure)
Perform the following reflections:
Point A: (-1, -7)
Point AI : _______
Wrap-it-Up/ Summary:

5)
Reflection across the x axis:
6)
Reflection across the y axis:
Remember: “RIGHT or LEFT changes X, UP or DOWN changes Y!!
7)
Reflection across the x-axis:
Hint: Flipping over x is an UP or DOWN flip!
8)
Reflection across the y-axis:
Hint: Flipping over y is a RIGHT or LEFT flip!
9)
Write a rule to describe the below reflection:
Hint: Look for the prime marks!!
