The transformations rule for changing DEF into D"E"F is
(b) T-5,0-RO. 90° (x,y)
To transform a shape is to alter its dimensions and relative placement.
To convert from DEF to D"E"F, use this rule:
(b) T-5,00 RO, 90°(x, y)
From the complete question,
When DEF is spun 90 degrees counterclockwise, it becomes GH.
Then, 5 units were subtracted from the right and translated to the left.
Assume a rotation of 90 degrees counterclockwise, and write it as:
RO, 90°(x,y)
As a symbol, the leftward translation of 5 units looks like this:
T-5,0(x,y)
When both transformations are combined, we have:
T-5,0 R0.90° (x. y)
In conclusion, the transformations rule for changing DEF into D"E"F is
(b) T-5,0-RO. 90° (x,y)
