1. two students created a list of steps for the following construction. you are given ab and point c. construct a line
parallel to ab that passes through point c.
student a
draw a line that intersects points b and c.
draw a line through point c and point g.
which student has steps in the correct
order, and which does not? explain.
keep the compass at the same width, and place
it on point c.
keeping the compass at the same width, place it
on point f.
mark the intersection of the two arcs as point g.
student b
draw a line that intersects points b and c.
place the compass on point b and swing an arc
that crosses line ab and line bc. label the
points d and e.
keep the compass at the same width, and place
it on point c
swing an arc that crosses line bc, and label the
point f.
open the compass to the width between points
d and e.
keeping the compass at the same width, place it
on point f.
swing an arc that intersects the arc created from
line bc at point c
mark the intersection of the two arcs as point g.
oint g
draw a line through point c and point g.
open the compass to the width between points
d and e.
place the compass on point b and swing an arc
that crosses line ab and line bc. label the
points d and e
swing an arc that crosses line bc, and label the
point f
swing an arc that intersects the arc created from
line bc at point c.
