A rotation of 30 degree

Question

What does it mean if an object moves 30 degree ? What will be its position now ? ( The concept of angles looks abstract to me. I cannot visualise it.)

Thanks!

Answer 1

Draw a circle and trace it with a pencil counter-clockwise.

Every time that you trace the whole circle you have rotated your starting point $360$ degrees.

If you only go a quarter circle then you have rotated $90$ degrees.

For a $30$ degree rotation you have to only rotate a third of a quarter around.

Remember a whole turn around a point is $360$ degrees.
