M
fi

E
F​

Answer 1

Answer:

(1) Two line segments are congruent if they are of equal length.

On measuring the lengths of AB and CD by a divider,

we find that length of AB = length of CD

∴ The line segments AB and CD are congruent.

(2) Two line segments are congruent if they are of equal length.

On measuring the lengths of LM and UV by a divider,

we find that length of LM ≠  length of UV.

∴ The line segments LM and UV are not congruent.

(3) Two line segments are congruent if they are of equal length.

On measuring the lengths of GH and EF by a divider,

we find that length of GH = length of EF.

∴ The line segments GH and EF are congruent.

(4) Two line segments are congruent if they are of equal length.

On measuring the lengths of LN and SM by a divider,

we find that length of LN ≠ length of SM.

∴ The line segments LN and SM are not congruent.
