Construction Assessment
PSC Geometry Honors
Name_______________________ Period____
Directions: For this assignment, you will need to learn and practice the 7 basic constructions.
This assignment will be graded on completion, accuracy and creativity (see rubric at end of assignment).
You are to do this entire project on your own with NO COLLABORATION. You have many tutorials and
other webpages to help guide you. You may see me if you are having problems.
Be sure what you turn in is complete and neatly done.
All constructions MUST be done in pencil.
Do not erase marks unless they are mistakes – all necessary arcs and markings MUST be there.
Any explanations should be in complete sentences with attention to proper spelling, grammar, and
usage.
Be sure to print this assignment out because you will need to write/mark on some of it.
Materials needed:
Compass
Straight edge
Pencil
Colored pencils or crayons
Paper
Basic Constructions:
Congruent segment
Perpendicular bisector
Perpendicular from point on a line
Perpendicular from point not on a line
Congruent angle
Angle bisector
Line parallel to a given line
Using the list of resources below, review/learn and practice the constructions listed above. You should take
notes and practice until you have mastered each one. You should make a construction section in your
notebook so that when all of your papers are returned you can keep them in your notebook as a reference.
We will use these basic constructions throughout the year.
Resources for learning constructions:
Brightstorm: www.brightstorm.com/math/geometry - there is a whole section for constructions
Mathisfun: http://www.mathsisfun.com/geometry/constructions.html - click on links for the constructions
you want to see
GeoOnline: http://teachers.henrico.k12.va.us/math/HCPSgeo/G-4-1.html
There are links for Construction Videos, or look at any other information/websites there that may be
helpful.
Flipchart: We will view this later. You can practice using construction tools with this software. Explanations
are found here as well.

Part 2: 1/9/15
In this section, you will use the basic constructions to construct figures we have studied so far this year.
You may need to refer to your vocabulary and/or notes. Again, all constructions should be done on
separate paper, with each one labeled. For each construction, write a brief description of your method.
This assignment will count as part of a test grade.
1.
Construct a b with transversal t . Begin by drawing a and t using a straightedge, and placing
point T on the transversal. Based on what you know about parallel lines and corresponding
angles, construct b that goes through T so that the lines are parallel.
2.
Construct c d with transversal v . Begin by drawing c and v using a straightedge, and placing Q
on the transversal. Based on what you know about parallel lines and alternate interior angles,
construct d that goes through Q so that the lines are parallel.
B

3.
Construct a right isosceles triangle
4.
Construct an equilateral triangle
5.
Construct a square
6.
Construct a regular hexagon
7.
For each of the following, construct BRK based on the segments and/or angles given. State
which congruent triangles theorem/postulate you used for each (SAS, AAS, ASA, HL, SSS).
Use the segments and angles below for this section.

Part 3: Due 1/15/15
Now is time to have some fun and let the creativity flow! You are to use each of the basic constructions at
least once to design a logo, create a floor tile or fabric design, or design a building. This should be
something original (that YOU created). The only tools you should use for this are a compass and a straightedge on a blank sheet of paper. You may decorate once you are done with colored pencils and/or crayons
as long as the construction markings are still clearly visible. Along with your creation, on a separate sheet
of paper, you are to include a written portion that identifies and describes all angles and triangles, along
with a description of what you have constructed, why, and what you have learned by completing this
assignment.
