Answer one and two please.

1) triangle qtr and triangle ate are congruent ( you can say asa or sss). In is specie example you can write either of these.
You can write asa because we are given two angles that are congruent and a side that is shared by both triangles ( which is side qt).
You can write sss because we are given two sides that are congruent and a side that's shared by both triangles ( which is side qt)
2) triangle abc is congruent to triangle def ( you can say asa)

Hope this helps ;)
