Answer:
1) 
2) 
3) 
4) 
Step-by-step explanation:
Let's assume that we have the following four cases in the figure attached.
In order to create inequalities related to the possible angles between the two triangles for each case we ned to use the following theorem:
Hinge theorem""If two sides of one triangle are congruent to two sides of another triangle, and the included angles are not congruent, then the longer third side is opposite the larger included angle"
Part 1
For this case we have that the angle
and from the graph we know that the angle
so then we have that angle
so then we can conclude from the theorem above that:

Part 2
For this case we have that the angle
and from the graph we know that the angle
so then we have that angle
so then we can conclude from the theorem above that:

Part 3
For this case we have that the angle
and from the graph we know that the angle
so then we have that angle
so then we can conclude from the theorem above that:

Part 4
For this case we have that the angle
and from the graph we know that the angle
so then we have that angle
so then we can conclude from the theorem above that:

In this question we have to use the formula:

Substituting the values of the intercepted arcs in the formula, we will get

And angles 1 and 2 are linear pair.
So we will get

Substituting the value of angle 1, we will get

Math Sucks hahahahahahahahahahahahaha
