question

GI
and
JL
are
parallel
lines.

Which angles are alternate interior angles?

LKH and JKH

LKH and JKM

LKH and LKM

LKH and GHK

key idea

A transversal is a line that intersects two other lines.

Two angles formed by a transversal crossing two lines are alternate interior angles if they are between the two lines and are on opposite sides of the transversal, but are not adjacent.

solution

The
transversal
is
FM
.

First find LKH.

Check each pair of angles.

LKH and JKH are not alternate interior angles. They are adjacent angles.

LKH and JKM are not alternate interior angles. JKM is not between the parallel lines.

LKH and LKM are not alternate interior angles. They are on the same side of the transversal.

LKH and GHK are alternate interior angles.

They
are
between
GI
and
JL
and
are
on
opposite
sides
of
the
transversal,
but
they
are
not
adjacent.
