Thought Today
Name 4 different kinds of
angle pairs that are created
when 2 lines intersect
Supplementary
Angles
Vertical Angles
Adjacent Angles
Linear Pair
Vocabulary Word - #55
TRANSVERSAL
A line that
intersects two or
more coplanar
lines at different
points
What’s a good
DESCRIPTION
(Picture or Example)
for today's
word?
You MUST pay attention
to the lines!! Which
ones are the ‘TWO
LINES’ & which ONE is
the TRANSVERSAL!
You know that when 2 lines
intersect several kinds of
angles are created
Obtuse Right Acute Perpendicular
Linear Pair
Vertical Angles
Adjacent Angles
Supplementary
Angles
When 2 lines are crossed
by a TRANSVERSAL several
different kinds of angles
are created!
Corresponding

Each person needs 3 colored
sheets of paper
line them up and spread them out
from the bottom about a fingers
width each
fold the top down to the middle and
you should have 6 colored edges
showing (the 2 middle will be the same color)
Holding the sheets together, lift up
the top 3 tabs and staple the
sheets together at the top on both
sides
