Class 5 Mathematics Maths-Mela Chapter 3 Angles as Turns question answer
When Reema makes two half turns in the same direction, the turns add up. One half turn means she turns halfway around. Another half turn makes the remaining half. Together, these two halves complete one whole circle. This is called a full turn. A full turn brings her back to the exact place from where she started, just like the hands of a clock after completing 60 minutes.
