It's not valid because there are too many unknown quantities, meaning there is not exactly one triangle that could exist for any given SSA combination.
For a visual example, see the attached image below.
It's fairly obvious that . One is acute, the other is obtuse. In the triangle on the right, the dashed side has the same length
as in the triangle on the left. This dashed side and the actual side
form an isosceles triangle with congruent base angles
. The angles
and
are supplementary (they add to 180 degrees), or
.
Now by the law of sines, in the first triangle,
and that in the second triangle,
but we also know that . Hence
.
Two different angles in this arrangement allow for two different triangles to be constructed, so having a SSA correspondence between two triangles is not enough evidence for their congruence.

here's the answer I have in the photo and solution too
Answer:
A= 10 units squared
Step-by-step explanation:
Because we are fully given points A and B, as well as the knowledge that ABC is a right triangle, we can assume that point C is the last needed point to form the right angle of this triangle. Meaning, point c has to have <em>one</em> identical coordinate out of (x,y) that is the same from <em>each</em> of our pre-existing coordinates in order to successfully form a right angle.
Due to the fact that we are told that Point C lies on y=2, we know that it already has an identical 'y' coordinate as Point A.
We can now decode that the x coordinate of Point C must be identical to the x coordinate of Point B, In this case, -2
We can conclude that point C lies on (-2,2)
If we look at the length of the sides of the triangle, ignoring the hypotenuse, we can see that one is 4 units long and the other is 5 units long.
To find the area of a square the formula is A= l x w x 0.5
Since 4x 5 = 20 and half of 20 is ten, we know that the final answer will be 10 units^2
to help you visualize this problem I've added an attachment :)
