HI, I wanted to make different forms turn around the four corners, but it doesn't work. help?

The forms rotate nicely around the upper left and under right corner, but I can't get other forms to rotate around the under left corner. Instead of rotating around that corner, it made the range bigger and rotated around the upper left corner. I hope it is clear now and that someone can help me. I tried to do that at line 23-25.

float theta;
int i = 0;


void setup() {
  size(750, 750);
  background (130);
  frameRate(60);
  smooth();
}

void draw() {
  if (i < 72) {    
    translate(width-40, height-50); // right under corner
    rotate (theta);
    drawShapes();                 // all the shapes, written at void drawShapes
    rotate (-theta);

    translate(-width+40, -height+50); // left upper corner
    rotate (theta);
    drawShapes();                 // all the shapes, written at void drawShapes

      translate(0, height-50); // left under corner
    rotate(theta);
    drawOthers();            // all the shapes, written at void drawOthers


      theta += radians(5); // rotation   
    i++;
  }
}

void drawShapes() {
  noStroke();
  fill(#C347FA);                 // all kinds of forms and fills
  ellipse(20, 30, 20, 20);

  stroke(#47FACE);
  line(25, 56, 36, 75); 
  line (36, 75, 18, 103);

  noStroke();
  fill(#47DDFA);
  triangle(25, 125, 42, 145, 18, 170);

  stroke(#FF0527);
  line(45, 175, 6, 200);
  line ( 6, 200, 55, 225);

  noStroke();
  fill(#FFFF98);
  ellipse( 20, 250, 20, 20);

  stroke(#D598FF);
  line( 45, 275, 6, 300);
  line ( 6, 300, 55, 325);

  noStroke();
  fill (#63B267);
  triangle(25, 350, 42, 370, 18, 395);

  stroke(#08B9FC);
  line(25, 415, 36, 425);
  line(36, 425, 18, 435);

  noStroke();
  fill(#FF79BC);
  ellipse(20, 480, 20, 20);
}


void drawOthers () {                  // more kinds of forms and fills
  fill(#FA0A0A);
  ellipse(10, 10, 10, 10);
}

Please read this: https://forum.processing.org/two/discussion/15473/readme-how-to-format-code-and-text

Please also include exactly what you mean when you say it doesn't work. What exactly do you expect this code to do? What exactly does it do instead? How are those different? What line does that difference start?

I think this code would benefit from pushMatrix / popMatrix to isolate all the transformations.
