A. draw the image of δdef after a rotation of 90° clockwise about the point (1,0). label the image δd’e’f’.
b. draw the image of δd’e’f’ after a reflection across the line x = 1. label the image δd”e”f”.

  see the attachment

Step-by-step explanation:

(a) Clockwise rotation moves a point from (x, y) to (y, -x).

__

(b) Reflection across x=1 moves a point from (x, y) to (2-x, y).

x is variable or an unknown value to find

example:

2x = 5 which means x = 3
