Suppose we have a map with North, South, East, West Map

If we move from

Right angle and straight angle - Part 2

We have rotated ‘right angle’ in clockwise direction.

We see that

  We have rotated 1/4 of the full turn.

  So, right angle is 1/4 of the full rotation

 

If we go from

  East to South

Right angle and straight angle - Part 3

We have rotated right angle in clockwise direction

 

Now, if we go from

  South to North clockwise

Right angle and straight angle - Part 4

We have rotated 1/2 revolutions.

This is straight angle .

  2 right  angle = 1 straight angle

 

Similarly,

  If we go from East to West Clockwise

Right angle and straight angle - Part 5

Then we have rotated 1/2 revolution

  i.e.  we have rotated

    1 straight angle

 

Suppose,

  We go from North to North

Right angle and straight angle - Part 6

In this case,

  we have rotated 1 revolution

  ∴  we have rotated 1 full angle

 

In Summary

Right angle and straight angle - Part 7
