MN - MP
Angle-angle-side congruence
Corresponding sides of congruent figures have equal
lengths.
What was the first mistake in Liliana's proof?
Choose 1
mZMPN was not given.
B
Liliana failed to establish the conditions for the angle-angle-side criterion
The angle-angle-side criterion does not guarantee congruence.

Sides MN and MP
are not corresponding sides of congruent triangles.
