Making a perfect spinning triangle

Ejemy

Heyo, So I'm new and having trouble making a triangle that spins from the center and all. I want to make a little animated fidget spinner so I'm starting with a triangle. Here's my code so far but the triangle seems good when it's right way up but when it spins it's obviously not and it's late and I can't figure it out.

Thanks.

float velocity = 0.01; float spin = 0;

void setup(){ size(500,500);

}

void draw(){ background(255);

spin += velocity; pushMatrix(); translate(width/2, height/2); noStroke(); fill(0); rotate(spin); triangle(0,-100, 100, 50,-100,50); popMatrix(); noStroke(); fill(255,0,0); ellipse(width/2, height/2, 5, 5);

}

My code didn't paste very well from Processing....

The triangle you posted does already spin exactly from the center,
it's just not an Equilateral_triangle

float velocity = 0.01; 
float spin = 0; 
float size=100;

void setup() { 
  size(500, 500);
}

void draw() { 
  background(255);
  spin += velocity; 
  pushMatrix(); 
  translate(width/2, height/2); 
  noStroke(); 
  fill(0); 
  rotate(spin); 
  triangle(size,0, 
    cos(radians(120))*size, sin(radians(120))*size, 
    cos(radians(240))*size, sin(radians(240))*size
    );
  popMatrix(); 
  noStroke(); 
  fill(255, 0, 0); 
  ellipse(width/2, height/2, 5, 5);
}
