In this lesson, we will learn
Since AB and PQ are both perpendicular to ST, these 2 lines are parallel.
This property can be used to construct two parallel lines.
Construct a line parallel to AB and 2 cm above it.
Step 1 : Mark a point C anywhere on the line AB. Construct a line perpendicular to AB and passing through C.
Step 2 : Construct a line segment on the perpendicular line 2 cm above C. Label the point as D. Then, construct a line perpendicular to CD and passing through D. This line is parallel to AB.
