Answer:
1) Segment AB =d
2) Length of segment AB = b
3)MN=c
4)
is congruent to = a
Explanation:
We are supposed to match the items
Options:
a.

b. AB
C. 7
d.

1) Segment AB
So, D option denotes the segment
So, 1) Segment AB =

2) Length of segment AB = Option b
So, Length of segment AB =AB
4)
is congruent to
So, referring the given figure we can say
is congruent to

So,
is congruent to option a
3)MN
Since
is congruent to
(by 4)
So, KL = MN = 7
So, MN = 7
So, MN = option c
Hence
1) Segment AB =d
2) Length of segment AB = b
3)MN=c
4)
is congruent to = a
