Draw a line segment AB. Mark a point L approximately 3 cm above AB. Through L draw LM∥AB.
Step 1: Draw a line AB
Step 2: From point A draw AX⟂AB
Step 3: On ray AX mark point L such that AL=3cm
Step 4: At L draw LM⟂XA
Here, line LM is parallel to AB
Draw a line segment AB = 6.2 cm. Mark a point P in AB such that BP= 4 cm. Through point P draw perpendicular to AB.
