Geometric Constructions with Lines and
Angles: Mastery Test correctly answered
Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction
bar.
In the given diagram, two sets of arcs are drawn above and below segment AB using a compass set to
the same width. For one set of arcs, the compass needle is positioned at point A. For the second set of
arcs, the compass needle is positioned at point B. A line drawn through the intersections of these two
sets of arcs determines the location of point C. - correct answer ✔✔Based on this construction, CB = 16
units and AB =--- units.
What is the first step in the construction of a line perpendicular to AB ⟷ and passing through an
external point M? Assume that the construction uses only a compass and a straightedge. - correct
answer ✔✔Place the compass needle on M and, keeping the compass width the same, draw two arcs
that intersect AB⟷.
Select the correct answer from the drop-down menu.
The diagram shows a stage in the construction of a line perpendicular to GH― through point A.
The next step in this construction is - correct answer ✔✔to keep the same compass width and draw an
arc centered at H crossing the previous arc in the image
When using a reflective device such as a Mira to bisect angle ABC, where should the reflective device be
placed? - correct answer ✔✔Place one end of the reflective device on the vertex B and swing the other
end until you can see the reflected line segment BC coincide with line segment AB.
Drag each tile to the correct box. Not all tiles will be used.
Given a horizontal line segment AB and a point C, place the steps for copying AB to create CD in the
proper order. - correct answer ✔✔1st Set the compass width to AB
