Answer:
- 2) None, 4) ASA, 6) ASA, 8) ASA
Step-by-step explanation:
#2
We have two parallel sides.
This gives us two pairs of alternate interior angles and one pair of vertical angles.
In total 3 congruent angles. This is not enough to state congruence.
None
#4
We have two pairs of congruent angles and an included common side.
This is good to state the triangles are congruent by ASA
#6
Similarly to above question, we have two pairs of congruent angles and an included common side.
This is good to state the triangles are congruent by ASA
#8
We have one pair of congruent sides and the parallel sides gives us two pairs of alternate interior angles and a pair of vertical angles.
We can state the triangles are congruent by ASA as the congruent side is included.
