What is the use of a tracing method? What are the Disadvantages of Comparison of Line Segments by Tracing.

Is circle a polygon? Answer with a reason

Explain positional error due to use of a ruler and divider. If the ruler is placed on a line segment and observed starting point at $4 \mathrm{cm}$ and $12 \mathrm{cm}$ instead of $4.2 \mathrm{cm}$ and $11.8 \mathrm{cm}$. Find the original length of line segment.

What are the Disadvantages of Comparison of Line Segments by Tracing.

Why ruler is not a better instrument, while measuring the length of a line segment?

Explain positional error due to use of a ruler and divider. If the ruler is placed on a line segment and observed starting point at $3 \mathrm{cm}$ and $12 \mathrm{cm}$ instead of $3.1 \mathrm{cm}$ and $11.9 \mathrm{cm}$. Find the original length of line segment.

Explain positional error due to use of a ruler and divider. If the ruler is placed on a line segment and observed starting point at $2 \mathrm{cm}$ and $15 \mathrm{cm}$ instead of $2.3 \mathrm{cm}$ and $14.7 \mathrm{cm}$. Find the original length of line segment.
