D) not possible
SAS won't work because the angles marked are not between the side lengths with the tickmarks
AAS won't work because we only have one pair of angles, not two. ASA is a similar story.
So that leaves "not possible" as the only answer. We simply don't have enough info. The triangles could be congruent, or they may not be. We simply don't know.
A y = -x+2
To find the slope of the line m we use the formula
slope = (y2-y1)/(x2-x1)
When lines are parallel, the slopes are the same. We need to find a line with slope of -1
y = -1x+2 is written in the form y =mx+b where m is the slope
m=-1 so the slope is -1
This line has the same slope so it is parallel to the line above.
D. Hydrogen Bonds
Angle angle side.
The answer is C. ASA
The SAS doesn't work here, and there are not two angles right next to each other to use.
would be A
SLOPE HAS TO BE -1
