Final answer:
To draw the opposite pattern of the original pattern using a nested loop, you can use a second nested loop that moves the turtle backward.
Step-by-step explanation:
To draw an additional pattern that is the opposite of the original pattern, you can use another nested loop. This time, instead of moving the turtle forward, you would move it backwards. For example, if the original pattern moves the turtle forward 100 units, you can draw the opposite pattern by moving the turtle backward 100 units. Here's an example of code:
import turtle
for i in range(4):
for j in range(4):
turtle.forward(100)
turtle.left(90)
for i in range(4):
for j in range(4):
turtle.backward(100)
turtle.right(90)
turtle.done()
