// right line
Line (85-A) (30-A) (40-A) (85-A)

Create a program that uses one variable as a means to control a set of 3 lines. Capture 3 instances of the graphic (A,B,C).
 
Part 3
p3.dbn 
Paper 45
// type program here
Repeat A 10 90

Part 4
p4.dbn 
Paper 40
Repeat A 0 80
{
  Pen (A*A/90)
  Line (A+10) (30-(A/4)) (A+10) (30+(2*A/3))
}

Create a program to draw a single filled triangle. Use your good judgement.
 
Part 5
p5.dbn 
Paper 60
Repeat A 0 45

   Pen A
   Line (A+15) (40-(A/2)) (A+15) (40+(2*A/3))
}
Repeat A 45 82
{
   Pen A
   Line (A+15) (2*(A-45)+20) (A+15) (40+(2*A/3))
}

Think of all the ways you can draw a filled triangle, and choose one. Utilize the properties of the drawing method you choose, to create a single filled triangle.

Part 8
p8.dbn 
Paper 100
Repeat A (-25) 25
{
   Repeat B (-25) 25
   {
      Set [(A+50) (B+50)] ((A*A+B*B)/5) 
   }
}

Using a nested loop, fill the entire field with the value of some calculation that can be appreciated. Do not use the Line command.
 
Part 9
p9.dbn 
Paper 0
Repeat A 0 25
{
   Repeat C 1 16
   {
      Repeat B 0 5
      {
         Set [(4*A) (4*B+C*5)] 100
      }
   }
}

Using a nested loop, create a stippled pattern of dots that can be enjoyed for its complexity. Do not use the Line command.
 
Part 10
p10.dbn 
Paper 40
Repeat A 0 30
{
   Repeat B 0 30
   {
      Pen (2*A+10)
      Line (A+20) 20 (A+20) 50
      Line (A+20) 50 (A+30) 60
   }
}
Repeat A 0 10
{
   Repeat B 0 30
   {
      Pen (70-(6*A))
      Line (A+50) (A+20) (A+50) (A+50)
   }
}

Using the Line command, and a (few) nested loop, create an image that evokes a three-dimensional feeling through shading.
