Question 11

What is the correct way to create a turtle object named fred?

Answer 11

fred= turtle.Pen()

Question 12

When we are entering numbers for our turtle to move, the unit we are using is ______.

Answer 12

The unit we are using is pixels. These are the tiny dots that your computer screen is made up of. You might have heard of a term called the “resolution” of your monitor, which could be something like 2304 by 1440. That means that the computer monitor has 2304 pixels the long way and 1440 pixels the short way. So pixels are pretty tiny!

Question 13

How do you move a turtle forward?

Answer 13

t.forward(30)
Let’s say if you want to move the turtle forward by 30 pixels
When the turtle moves, there will be a black line (by default) connecting from where it began to where it is now.

Question 14

How do you move the turtle backward?

Answer 14

t.backward(30)
This command makes the turtle go back to where it came.

Question 15

Let say the turtle is the shape of an arrow. Which direction would the arrow of the turtle be facing when there is a command to move it backwards?

Answer 15

The arrow will look like that

Question 16

What does the left and right command do?

Answer 16

The left and right command rotates your turtle. They don’t have it move forward at all. The left and right commands work in degrees not in pixels.

Question 17

Where would the turtle be after these lines of code?
import turtle
t= turtle.Pen ()
t.forward (30)
t.backward (30)
t.left (30)
t.forward (30)

Answer 17

/__
Something like that but the lines are connected.
The line is slanted because of the command t.left (30) so 30 is the angle.

Question 18

The direction of the turtle arrow would always be at the right side. Is that true or false?

Answer 18

True

Question 19

What is the clear function?

Answer 19

The clear() function removes the line that you were drawing, but it leaves the turtle right where it is.

Question 20

What is the reset function?

Answer 20

The reset() function also removes the line that you were drawing, but puts the turtle back in the Center of the screen.

Question 21

Can you figure out how to draw a square using by using t= turtle.Pen() ?

Answer 21

Square= turtle.Pen ()
Square.forward(40)
Square.right (90)
Square.forward (40)
Square.right (90)
Square.forward (40)
Square.right (90)
Square.forward (40)
