Answer:
Triangles A and C are congruent.
Explanation:
Congruent triangles are when two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The total of the angles of all triangles is 180, so then add all the angles then subtract that number from 180.
A: 110+30=140 (180-140=40)
B: 30+45=75 (180-75=105)
C: 110+40=150 (180-150-30)
Since Triangles A and C have the same angles, then they are congruent!!!
