Robot tip (Count the degrees): Full turn 360°, half turn 180°, right angle 90°. Heading: right adds, left takes away; keep it between 0° and 359° by adding or taking away 360. Equal turns in a full circle = 360 ÷ one turn; time to turn = angle ÷ degrees per second.

  1. 1.🧭 A robot’s gyro reads 0° when it faces north and counts up to 359° as it turns right (east is 90°). It starts at 180°. It turns left 45°, then left 90°. What does the gyro read now (0° to 359°)?
