The straightedge can only be used to draw a straight line, or check to see if a surface is flat, but cannot measure length. A ruler can be used to draw a straight line or check for flatness, and a ruler can also measure length because it has evenly spaced markes denoting inches and centimeters.

Using a compass and ruler: # At the point you want the perpendicular line to cross, place a dot. Label it A. # Draw a circle centred at A with a radius of about an inch (two-three centimetres). Label the points it intersects the original line as B and C. # Construct two circles centred at B and C, large enough that they almost reach the other point and have the same size. Label the points they intersect at as D and E. # Draw a straight line between E and D. This line is the perpendicular line. This method can also be used to draw a perpendicular bisector, if the ends of the line you wish to bisect are labelled as points B and C.

i don't know u tell me

It is impossible to draw a straight line.

The compass is used to measure angles. The straightedge is used to draw a straight line. The two items together, are used to measure and draw angles and lines in geometric drawings.

True

Use a straightedge to draw a line segment from A to one of the points where the two circles intersect.

Yes

Take a compass. Open it so that it is a large enough radius to be easy to draw, but small enough that it still marks on both lines of the angle. Draw an arc that crosses both lines making up the angle, then place the point on each of these intersections and draw two more arcs of the same size so that they intersect. Using a straightedge, draw a line from the point of the angle to the intersection. That is the bisecting line.
