It takes 4 90 degree angles to make a full circle
3
It takes four times because 45+45=90+45=135+45=180. So all of those angles can make a straight line.
A polygon having 30 degree exterior angles is a dodecagon having 12 sides.

There are 360 one degree angles in a full turn
It takes 4 90 degree angles to make a full circle
It takes: 360/40 degrees = 9
A full turn is 360 degrees, so it would take three 120 degree turns.
Perpendicular lines make four 90 degree angles otherwise known as right angles.
3 times.

Four 90 degree angles.
There are 4 - 90 degree angles
A full turn is 360 degrees, so it would take three 120 degree turns.
