This interactive applet allows to drag point "B" to verify that two triangles remain congruent
when you have two pairs of corresponding angles, and a pair of non-included sides congruent.
You may drag point "B" to verify that when two pairs of corresponding angles in a triangle, and the one pair
of included sides are congruent the triangles are congruent.
Congruency that may verified by moving point "B". Observe that the congruence for the
two triangles remain true when you have two pairs of corresponding sides, and the included angle congruent.
This is the congruence where you have all three corresponding sides in two triangles congruent.
Play with point "B" to verify it.
