Answer:

The "draw the tree" step will look like this:

' Draw the Tree 

'   Draw the Trunk 
LINE (510, 400)-(510, 240)
LINE (540, 400)-(540, 240)

'   Draw the Leaves 
CIRCLE (525, 160), 80

The Tree

This is a fairly crude tree, made up of just two lines and a circle. You might want to divide the "draw the tree" step into many more steps that draw the trunk more realistically, and (maybe) draw the leaves using several overlapping smaller circles.

But let us move on and draw the grass. The grass looks like this:

A line from the left edge of the picture to the right edge of the house.
A line from the right edge of the house to the tree.
A line from the tree to the right edge of the picture.

To add a bit of interest to the picture, the lines will not be horizontal.

QUESTION 20:

Think about how this step will look.
