Ido not understand this. and can you explain it for me when i use it again? 1. a rectangular prism is defined as the drawing shows. note b at (0, 5, 0) and f (0, 0, 4). the prism is reflected over the xz-plane. the reflected image is then translated 2 units back, 3 units left, and 1 unit up. a.) show the results of your calculations for points a, b, c and d from the reflection. b.) show the results of your calculations for points a, b, c and d from the translation. here is the image- 

Let's start b writing down coordinates of all points:
A(0,0,0)
B(0,5,0)
C(3,5,0)
D(3,0,0)
E(3,0,4)
F(0,0,4)
G(0,5,4)
H(3,5,4)

a.) When we reflect over xz plane x and z coordinates stay same, y coordinate  changes to same numerical value but opposite sign. Moving front-back is moving over x-axis, moving left-right is moving over y-axis, moving up-down is moving over z-axis.

A(0,0,0)
Reflecting
A(0,0,0)

B(0,5,0)
Reflecting
B(0,-5,0)

C(3,5,0)
Reflecting
C(3,-5,0)

D(3,0,0)
Reflecting
D(3,0,0)

b.)
A(0,0,0)
Moving
A(-2,-3,1)

B(0,-5,0)
Moving
B(-2,-8,1)

C(3,-5,0)
Moving
C(1,-8,1)

D(3,0,0)
Moving
D(1,-3,1)

I’m not gonna do that
