Question

Draw a line AB. Mark a point Con it and draw
a perpendicular to AB from it. Take a point
D on this perpendicular 6 cm away from C.
Through D, construct a line EF parallel to AB.​

Answer 1

Step-by-step explanation:

To construct: A-line, parallel to the given line by using ruler and compasses.

Steps of construction:

(a) Draw a line segment AB and take a point C outside AB.

(b) Take any point D on AB and join C to D.

(c) With D as a centre and take convenient radius, draw an arc cutting AB at E and CD at F.

(d) With C as a centre and same radius as in step 3, draw an arc GH cutting CD at me.

(e) With the same arc EF, draw the equal arc cutting GH at J.

(f) Join JC to draw a line l.

This is the required line AB || l.

Answer 2

Step-by-step explanation:

Draw a line AB. Mark a point Con it and draw

a perpendicular to AB from it. Take a point

D on this perpendicular 6 cm away from C.

Through D, construct a line EF parallel to AB.
