Six of them because 6 times 60 = 360 degrees which is a full turn
It take 6 turn to make a full turn
It takes 4 90 degree angles to make a full circle
10000
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.
8 of them.

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.
