In the figure, line a and line b are parallel. based on the figure, match each given angle with its congruent angles. angles congruent to < 1 angles congruent to < 2 angles congruent to < 7 angles congruent to < 6 match to these < 3,< 7,< 6 < 3, < 7, < 2 < 4,< 8,< 5 < 3,< 6,< 2

Part 1) angles congruent to <1

we know that
<4=<1> by vertical angles
<5=<1> by corresponding angles
<8=<5> by vertical angles or <8=<1 > by alternate exterior angles
so
the answer part 1) is
<4,<8,<5

Part 2) angles congruent to <2
we know that
<3=<2> by vertical angles
<6=<2> by corresponding angles
<7=<6> by vertical angles or <7=<2 > by alternate exterior angles
so
the answer part 2) is
<3,<7,<6

Part 3)angles congruent to <7
we know that
<6=<7> by vertical angles
<3=<7> by corresponding angles
<2=<3> by vertical angles or <2=<7 > by alternate exterior angles
so
the answer part 3) is
<3,<6,<2

Part 4) angles congruent to <6
we know that
<7=<6> by vertical angles
<2=<6> by corresponding angles
<3=<2> by vertical angles or <3=<6 > by alternate interior angles
so
the answer part 4) is
<3, <7, <2

He secknd step was the answer to them
