Answer:

101. ΔABC congruent to ΔDEF

102. ΔJKL not congruent to ΔMNO

Explanation:

Q 101

Triangle ABC has 3 sides equal to each of the three sides of DEF

The corresponding two angles of ABC and DEF are also equal

So the third angle of ABC ∠B must be equal to the third angle of DEF so we have three sides equal, three angles equal, hence congruent

ΔABC congruent to ΔDEF

Q 102

We have JL = MP = 1.9

m∠J = m∠M = 24°

The other two angles are not correspondingly equal

This only makes one side equal and one angle equal. Not sufficient to make it congruent

Hence ΔJKL not congruent to ΔMNO
