    size(500,500);

// the rectangle
stroke(255,0,0);
fill(255,0,0);
rect(400,400,100,100);

//the circle
stroke(0,255,0);
fill(0,255,0);
ellipse(50,50,100,100);

// the triangle
stroke(0);
fill(0,0,255);
beginShape();
vertex(150,150);
vertex(150,250);
vertex(300,200);
endShape(CLOSE);
    or if you wanted to use the predefined colours (in another tab): 
    void setup()
{
  size(500,500);
}

void draw()
{
  // the rectangle
  stroke(RED);
  fill(RED);
  rect(400,400,100,100);
  
  //the circle
  stroke(GREEN);
  fill(GREEN);
  ellipse(50,50,100,100);
  
  // the triangle
  stroke(BLACK);
  fill(BLUE);
  beginShape();
  vertex(150,150);
  vertex(150,250);
  vertex(300,200);
  endShape(CLOSE);
