Which construction is shown in the accompanying diagram?

You are asked to "construct" an angle whose measure is $$30^\circ$$. Which of the following methods would be considered as an acceptable construction? 

The instrument to measure an angle is a 

When a perpendicular is drawn to a given line, in what ratio is the line divided into?

Instrument used to measure or construct angles is-

How many arcs need to be constructed in order to draw an angle equal to a given angle?

Construct line $$\ l\ \ \parallel$$ line $$m$$, line $$l\perp$$ line $$n$$.

Which one of following is true?

Use a protractor to measure the angle $$x$$ as shown in the picture $$x$$ can be:

Using Protractor, we constructed an angle of $$45˚$$. The constructed figure looks like:

The steps for constructing a line segment of given length are given in a jumbled order below:
1. Draw an arc on the line by keeping the pointed end of the compass on the point $$A$$. Mark the arc point as $$B$$.
2. Draw a line.
3. Extend the compass by keeping one end on the $$0\ cm$$ mark and other at the given length on the ruler.
4. Take a point $$A$$ anywhere on the line.

Which of the above steps comes last?
