Question

Using a set square and a ruler draw a line parallel to the given line through a point $5cm$ above it.

Answer 1

Hint: Firstly, we need to draw a line segment AB of any length using the rule. Then we have to choose any point on it and label it as C. Now, keeping the corner of the set square at C, we have to draw a line CD of length $5cm$. Then, we need to place the ruler along the line CD. Then holding the ruler tightly, we need to slide the set square along the ruler so that the corner of the set square comes at the point D. Finally, we can draw the line DE along the edge of the set square, which will be the required line.

Complete step by step solution:
Step I: Draw a line segment AB with the help of the ruler and mark any point C on it.

Step II: Now, place the corner of the set square at C.

Step III: Draw a line CD of length $5cm$ using the set square, as shown below.

Step IV: Now, place the ruler along CD.

Step V: Now, slide the set square upwards along the ruler such that the corner of the set square comes at the point D.

Step VI: Finally through the base of the set square draw the line DE.

Hence, DE is the required parallel line passing through a point $5cm$ above the line AB.

Note: Take the help of the ruler so as to ensure the proper alignment of the set square for drawing the line parallel to the line AB. Draw the line CD very lightly, since it is not the part of the solution. We must ensure that the corner of the set square must be sharp.
