Question

Fill in the blanks in the following program so that it draws the given picture. Each

figure is a rhombus with side 100 and interior angles (60, 120, 60, 120). The distance

between 2 adjacent rhombuses is 20 (between their closest vertices).

repeat(2){

repeat(2){

B1;

left(B3);

B1;

left(120);

}

right(120);

penUp();

B2;

penDown();

repeat(2){

B1;

left(120);

B1;

left(B3);

}

right(B3);

penUp();

B2;

penDown();

}

What is command B1?

forward(100)

 

forward(20)

 

backward(100)

 

backward(20)

What is command B2?
