प्रश्न
Draw a line segment measuring 7.8 cm. Mark a point B above it at a distance of 5 cm. Through B draw a line parallel to the given line segment
उत्तर
Step 1: Draw a line. Mark two points M and N on the line such that MN = 7.8 cm.
Mark a point B any where above the line.
Step 2: Place the set square below B in such a way that one of the edges that form a right angle lies along MN Place the scale along the other edge of the set square.
Step 3: Holding the scale firmly, Slide the set square along the edge of the scale until the other edge of the set square reaches the point B.
Through B draw a line.
Step 4: The line MN is parallel to AB.
That is, MN || AB.
