After 6 iterations, the turtle has turned 6 × 60° = 360° , returning to its original heading. The shape closes perfectly. ❌ Using right(120) or left(120) ✅ Use left(60) – the exterior angle.
| Step | Action | Angle turned | |------|--------|--------------| | 1 | Forward (side length) | — | | 2 | Left 60° | 60 | | 3 | Repeat 6 times | — |
If you’re working through the CodeHS JavaScript or Graphics unit, you’ve probably hit 3.5.5: Hexagon . At first glance, it seems simple: just draw a six-sided polygon. But getting the angles right and placing it correctly on the screen can be tricky. 3.5.5 hexagon codehs
Now go submit that perfect hexagon and watch those green checkmarks roll in! ✅ Modify your function to draw a hexagon of any size from any starting point. Then try drawing a honeycomb pattern! 🐝
function drawHexagon(t, sideLength) for(var i = 0; i < 6; i++) t.forward(sideLength); t.left(60); // Exterior angle After 6 iterations, the turtle has turned 6
function start() var hex = new Turtle(); hex.penUp(); hex.goTo(100, 200); // Adjust starting position hex.penDown(); drawHexagon(hex, 50); // Side length = 50
❌ ✅ Make sure i < 6 (six sides).
hex.beginPath(); for(var i = 0; i < 6; i++) hex.forward(50); hex.left(60);
