Identify the parallel lines in English alphabets (Capital Letters) and list the letters.

Examples: 

Draw a line segment $\mathrm{LM}=6.5 \mathrm{cm}$ and take a point $\mathrm{P}$ not lying on it. Using a set square construct a line perpendicular to $\mathrm{LM}$ through $\mathrm{P}$.

Find the distance between the given lines using a set square at two different points on each of the pairs of lines and check whether they are parallel.

Draw a line segment measuring $7.8 \mathrm{cm}$. Mark a point $\mathrm{B}$ above it at a distance of $5 \mathrm{cm}$. Through $\mathrm{B}$ draw a line parallel to the given line segment.

Draw a line and mark a point $\mathrm{R}$ below it at a distance of $5.4 \mathrm{cm}$ Through $\mathrm{R}$ draw a line parallel to the given line.
