The equation we are looking at would have to be divided by 2 first. x²-6x+3 When looking at that, I can tell that 1 may be the possible answer since you would have to subtract 6 from both sides. That would leave a 3. Let's check. (x-3)(x-3) x²-6x+9=6 Now subtract 6 from both sides. x²-6x+3=0 So, 1- (x-3)²=6 would be used.
For my education system, there isn't such thing as SAS, ASA or etc. I just had to search it up what it was.
Congruent angles are angles with the same shape and size. The two triangles are congruent if you look carefully, after that I searched up and saw the different rules of triangles. I think that SAS might be the correct answer.
