this is the answer of your question

Answer 2

∴ $AB$ and $PQ$ in parallel at a distance of $3cm$

Step-by-step explanation:

Given;

Draw a line $AB$ parallel to $PQ$ at a distance of $3cm$

Following steps;

• Draw a line like $PQ$
• Mark any point on $PQ$ like $O$
• At point $O$, draw an angle $90degree$ and extend it like $OC$ by using compass as soon in figure.
• Mark $3cm$ on $OC$ like $D$
• At point $D$,again draw an angle $90degree$ by using compass like $DB$
• And extend it like $AB$

Now $AB$ and $PQ$ in parallel at a distance of $3cm$
