  2. X₁ — First X coordinate. Accepts values from -1,000 to 1,000 (default: 1).
  3. Y₁ — First Y coordinate. Accepts values from -1,000 to 1,000 (default: 2).
  4. X₂ — Second X coordinate. Accepts values from -1,000 to 1,000 (default: 2).
  5. Y₂ — Second Y coordinate. Accepts values from -1,000 to 1,000 (default: 4).
  6. X₃ — Third X coordinate. Accepts values from -1,000 to 1,000 (default: 3).
  7. Y₃ — Third Y coordinate. Accepts values from -1,000 to 1,000 (default: 5).
