Geometry B
Construction Review Sheet
Test is on __________
In order to do well on the construction test, be able to do the following:
I. The 4 basic constructions:
1. Copy a segment.
2. Copy an angle.
3. Perpendicular bisector.
4. Angle bisector.
II. The parallel and perpendicular constructions:
1. Construct a line parallel to a given line through a given point.
2. Construct a line perpendicular to a given line that passes through a
point on the line.
3. Construct a line perpendicular to a given line that passes through a
point off the line.
III. Apply your construction skills to problems involving angles,
triangles, and squares.
1. Equilateral triangle
2. Isosceles given the base and one side.
3. Triangle given all three sides (SSS).
4. Triangle given 2 sides and the included angle (SAS).
5. Triangle given one side and adjacent angles (ASA).
6. Specific angle measures (30, 45, 60, and 90 degrees).
7. Square given the side length.
Remember that a construction is done with a compass and straightedge only.
Be sure to use these tools, do not draw free hand.
In order to get full credit on a construction, it must be clear that you used the
compass and straightedge, therefore leave all your compass marks, do not
erase.
Use your notes and your homework to review the seven constructions we did
and the problems we applied them to.
