Since, it is given that the pentagon ABCDE is congruent to pentagon FGHIJ.

By being congruent, the corresponding angles and sides are equal.

Therefore,
\angle A = \angle F,
\angle B = \angle G,
\angle C = \angle H,
\angle D= \angle I,
\angle E = \angle J.

By using
\angle A = \angle F

So,
100^\circ = \angle 1

Therefore, the measure of angle 1 is 100 degrees.

So, Option B is the correct answer.
