an instrument use to construct straight line?
You construct a line perpendicular to the original and then a line perpendicular to this second line.
You can construct a parallel to a line through a point not on the line. (perpendicular line segment)
it would be perpendicular to the line.
Adjust the compass to the given line segment then construct the circle.
yes
Equilateral triangles
a pencil
A straight edge or a rule are used to construct straight lines. Laser line setter, In some cases a plumb line
Construct a perpendicular line through one side and intersecting the other. Then construct another line from that intersector and beginning at the point it intersects the second side. The two should be the same line.
