Tools in Geometry
TASK 1. Read the text on “Duplicating segments and angles” and complete the
following table:
Measuring tools
other geometry tools
TASK 2 . Read the text on “Duplicating segments and angles” and complete the
missing verbs:
Adjust
Construct
Draw
Extends
Figure out
Intersect
Label
Practice
Place
Sketch
Trace
Verify
TASK 3. Read the text on “Constructing perpendicular bisectors” and complete
the missing words:
Conjecture
Infinite
Converse
Intersecting
Equidistant
Locate
Endpoints
Midpoint
Vertex
TASK 4. Read the text on “Constructing perpendiculars to a line” and complete
the missing prepositions.
TASK 5. Read the text on “Constructing perpendiculars to a line” and find a
solution to the example.
TASK 6. The altitude of a triangle is a perpendicular segment from a vertex of a
triangle to the line containing the opposite side (base). The intersection of all three
altitudes of the triangle gives us the orthocenter. What do we get at the intersection of
a. medians
b. perpendicular bisectors of the sides
c. angle bisectors
TASK 7. Read all texts again with a partner and write a summary of the
construction methods you have come across so far in this lesson.
TASK 8. Note-taking task
Listen to the lecture and complete the missing student notes:
Technically
…………………………are
two
……………………..which means they share the same plane
or they're in the same plane that never…………………..
The way that you mark parallel lines is by
using………………………...
And
you
can
identify
parallel
lines
by
……………………………………….
So if there were two arrows on this top line xy and only one
arrow on wz = not parallel. However, if I …………….in a
second arrow here, then, from these markings I can
…………………………..that these two lines must be
parallel.
………………….lines are lines that are not coplanar
……………….can never intersect. So if we looked at
cube here, where we assume that we have
………………… here and that their opposite faces
parallel.
and
this
six
are
Parallel lines are two lines that never intersect you're going to
…………………..
because you're going to say they could be skew. Parallel lines
must be coplanar and they never intersect.
