Question

if we want to erase any part of the picture,which primitive will be used?​

Answer 1

Answer:

PENUP and PENERASE The PENUP or the PU primitive is used to lift the turtle's pen up from the screen. As a result, the turtle does not draw anything. On the other hand, the PENERASE or the PE primitive is used to make the turtle work as an eraser. The turtle starts erasing instead of drawing as it moves.
