Parallel line Theorems Flashcards
two nonadjacent angles,
one interior,and one
exterior on the same
side of the transversal
CORRESPONDING ANGLES
two non adjacent interior
angles on opposite sides
of the transversal
ALTERNATE INTERIOR ANGLES
two non adjacent exterior
angles on opposite sides
of a transversal
ALTERNATE EXTERIOR ANGLES
angles that lie between
the two parallel lines on the
same side of the transversal
SAME SIDE INTERIOR ANGLES
angles that lie outside
the two parallel lines on the
same side of the transversal
SAME SIDE EXTERIOR ANGLES
is a pair of
angles formed when two lines
intersect each other at a single
points. These angles are always
adjacent and supplementary
as they form on a straight line.
In other words, the sum of two
angles in a (blank) is always
180 degrees.
linear pair
in a linear pair is always (blank)
180 degrees
are coplanar lines or lines which lie
on the same plane that do not
intersect each other.
PARALLEL LINES
a line that intersects two or more
coplanar lines at two or more
distinct points.
TRANSVERSAL LINE BOGO
When two straight lines
intersect each other
what are
formed.
VERTICLE ANGLES
Vertical angles
are always what?
congruent and equal
If two lines are cut by a transversal,
then any pair of alternate interior
angles are congruent.
Parallel-Alternate
Interior Angle Postulate
If two lines are cut by a transversal,
then any pair of alternate exterior
angles are congruent.
Parallel-Alternate
Exterior Angle Theorem
If two parallel lines are cut by a
transversal, then the corresponding
angles are congruent.
Parallel-Corresponding
Angles Theorem
If two parallel lines are cut by a
transversal, then the interior angles
on the same side of the transversal
are supplementary.
Parallel-Interior Angles
Same Side Theorem
