Answer: A symmetry element is a line, a plane or a point in or through an object, about which a rotation or reflection leaves the object in an orientation indistinguishable from the original.
First of all there nothing exists something like SSA congruence criterion, It is SAS Congruence where the sides of a Triangle and the angle between them is exactly same to the other two sides and angle between them of another triangle.
So the correct option is D.
Explanation:
If the Triangle has two sides equal, so the two angles there are equal. Also the other angle be some other definite angle. So
45+x+x=180(Considering definite angle to be 45)
2x=135
x=67.5
So there is only one solution to the triangle.
Well the answer to number 1 is definitely B
number 2 is B
number 3 is D
Number 4 is C
