Describing the process in words is much more difficult than doing it. So I suggest you sketch out the steps as described. It will be much clearer that way!
1. Start with a straight East-West line.
2. Draw a line perpendicular to it - this will be North-South.
3. Now bisect the angle between West and South. This line will run from the centre to the SouthWest!
4. The angle between the line going East and this last line is 225 degrees.
by using a ruler and a compass
with compass.........at 90+60degree angle,,,,,,,,, * * * * * and 90 + 60 = 105??? You need to draw a 90 degree ange and bisect it to give a 45 deg angle. Then add a 60 degree angle. 45 + 60 = 105.
The supplement of an 80 degree angle is an 100 degree angle.
Construct a 90 degree angle isosceles triangle which will have equal sides and then divide the base into 9 equal parts joining the parts by lines to the apex of the trangle. Each line represents 10 degrees and 8 lines will equal to 80 degrees.
78 degree angle
An acute angle that is 1/4 of a right angle
With a protractor
Use a straight edge and a protractor to construct an acute angle of 65 degrees
A 40 degree acute angle can be constructed with a straight edge and a protractor.
Use a protractor.
Use a protractor or bisect a 45 degree angle with a compass and a straight edge
by 60 degree and 90 degree
With a protractor and a straight edge
With a protractor and a straight edge
use a protractor and a ruler
You'll also need a protractor to construct a 220 degree angle which can then be bisected by means of a compass and a straight line to form two 110 degree angles.
A 127.5 degree angle can be constructed by using a protractor and a straight edge.
