The takeoff for a 30 degree angle will depend with the offset angle.
Yes and they are both acute angles
a 60-degree angle
the 30 degree angle is near the equator and the 90 degree angle is near the trop of Capricorn and cancer
It is easy to draw an equilateral triangle without a protractor. That gives a 60 degree angle. It is then simply a matter of bisecting the 60 degree angle, using an unmarked rule and compass, to get a 30 degree angle.
30 degree angle
Yes.
a 60 degree angle is twice the size of a 30 degree angle.
The takeoff for a 30 degree angle will depend with the offset angle.
Yes and they are both acute angles
a 60-degree angle
staircase is made in an angle of 20 to 30 degree and it shouldn't be more then 30 degree.
If you bisect a 30 degree angle, you end up with two 15 degree angles.
A 60 degree angle
15 degrees. A bisected 60 degree angle makes 2 30 degree angles by definition of an angle bisector, then a 30 degree angle makes 2 15 degree angles by definition of an angle bisector.
the sine of a 30 degree angle is 0.5
the 30 degree angle is near the equator and the 90 degree angle is near the trop of Capricorn and cancer
