• forward(100)

When using the circle() command, what value do we put inside the parentheses?

• Radius of the circle

• Center of the circle

• Diameter of the circle

• Width of the circle

When Tracy is facing right, from what location does she start drawing the circle?

• Top of the circle

• Bottom of the circle

• Left of the circle

• Middle of the circle

Where does Tracy always start in the grid world?

• (0, 0) coordinate in the bottom left hand corner of the canvas

• (-200, -200) coordinate in the bottom left hand corner of the canvas

• (0, 0) coordinate in the middle of the canvas

• (-200, -200) coordinate in the middle of the canvas

What are the dimensions of Tracy's world?

• 200 pixels x 200 pixels

• 400 pixels x 200 pixels

• 400 pixels x 400 pixels

• 200 pixels x 400 pixels

How far does Tracy need to move from the starting position to reach the right side of the canvas?

• 50 pixels

• 100 pixesl

• 200 pixels

If you want Tracy to move forward 100 pixels without making a line, what set of commands should you write?

left(90)

left(90)

right(90)

• down

• right

• left

Which of the following is NOT a reason for loops are useful when writing code?

• Loops help use write the same program with fewer lines of code.

• Loops let us make shapes of multiple sizes

• Loops make it easier to alter code once it's written.

• Loops make our code easier to read

The following loop draws 3 circles on the screen.

for i in range(3):

circle(25)

forward
