an instrument use to construct straight line?
A spirit level or a plumb line.
An instrument to construct straight lines is called a rule. It's often referred to as a ruler, but a ruler is someone who rules a country. A rule is a piece of wood, metal or plastic (usually showing measurements) that you can use to draw/construct straight lines.A straight edgeThe most common one is a ruler
Use a straight edge and a protractor to construct an acute angle of 65 degrees
Well a straight line is something that you use in geometry and that is what you use to measure with.

To construct an angle of 127.5 degrees, start by drawing a straight line using a ruler. Next, use a protractor to measure and mark 127.5 degrees from one end of the line. Draw a second line from the point where you marked 127.5 degrees to create the angle. Finally, label the angle as needed to complete your construction.
you can use a ruler or a book or anything that has a straight line
Use a protractor and a straight edge to construct a 75 degree angle
Use a string for a straight line.
use a ruler
Use a protractor or bisect a 45 degree angle with a compass and a straight edge
Use a protractor or construct 2 perpendicular lines with a compass and a straight edge
