Question:

To construct a regular pentagon, what tools are required?

  1. Straight Edge, Compass, Pencil, Paper, Measuring Device
  2. Compass, Pencil, Paper, Measuring Device
  3. Straight Edge, Compass, Pencil, Paper
  4. Compass, Pencil, Paper, Measuring Device

Correct Answer: A

Explanation:

In order to know which tools are required to construct a regular pentagon first recall the attributes of a pentagon and the possible geometric tools used to construct figures.
A regular pentagon by definition is a five sided figure. All sides of the figure are equal and every interior angle measures 108°.
Geometric tools used to construct figures by hand include the follow:
Paper, Pencil, Compass, Ruler, Straight Edge, Protractor, Etc.
Geometric tools used to construct figures using technology include the following:
Graphing Calculators, Computer Programs, Etc.
Since the figure in question is a regular pentagon, to construct it by hand will require the use of a compass to ensure the angles are all equaled to 108°. Also, a straight edge is required to ensure the lines are straight and a measuring device such as a rule to ensure the side lengths are equal.
Of the possible answer choices, three list the Straight Edge, Compass, and Measuring Device. If these tools are being used then the figure is being drawn by hand therefore, pencil and paper are also required. Therefore, the correct solution is:
"Straight Edge, Compass, Pencil, Paper, Measuring Device"
