With a protractor
To make a 70-degree angle, you can use a protractor. Place the protractor's center point at the angle's vertex, ensuring one side aligns with the baseline of the protractor. Then, find the 70-degree mark on the protractor's curved edge and draw a line from the vertex through this mark. Alternatively, using a compass and straightedge, you can construct a 60-degree angle and then bisect it to create a 30-degree angle, adding them together to achieve a 70-degree angle.
A 40 degree acute angle can be constructed with a straight edge and a protractor.

Use a straight edge and a protractor to construct an acute angle of 65 degrees
180 - 70 = 110. The supplement is 110 degree angle.
A 40 degree acute angle can be constructed with a straight edge and 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.
