To translate â–ł PNB three units down, we have to subtract 3 from each y-coordinate.
(x,y) → (x,y -3)
Let's do this for the three vertices.
(x,y)
(x,y -3)
(x',y')
P(2, 2)
( 2, 2 -3)
P'( 2,-1)
N(3,-1)
( 3,-1 -3)
N'( 3,-4)
B(- 1,- 2)
(-1,- 2 -3)
B'(-1,-5)
With these points, we are able to draw transformed image as â–ł P'N'B'.
Reflection
To complete the reflection, we have to reflect all of the vertices of â–ł P'N'B' on the opposite side of the y-axis. The distance from the vertices to the y-axis remains the same. We will call the reflected image â–ł P''N''B''.
Final Glide Reflection
The final glide reflection is the combined translation and reflection.
