Use a ruler to make a right angle triangle of dimension 3,4,5 the angle adjacent to the side of 4 units length is 30 degrees.
Use a straight edge and a protractor to construct an acute angle of 65 degrees
Construct an equilateral triangle because each of its 3 exterior angles measures 120 degrees
asuming you know how to construct a 60 degree angle, you would start by drawling a basic construction line an then make your angle bisecter with breaks the angle into 30 degree angles. then create another angle bisector for 30 degrees breaking it into 15 degree angles. then do the same with the 15 degree angle. your drawling sould have three angle bisectors for each angle. to get your answer of 22.5 degress angle, simply add the 15 degree angle you drew with the 7.5 angle you got from spliting the 15 degree angle in half its hard to explain without drawing it out..... hope this helps
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

A 40 degree acute angle can be constructed with a straight edge and a protractor.
Use a protractor.

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.
