decide whether there is enough information to prove the following triangles are congruent. justify your answer for each pair of triangles.
is ∆abc ≅ ∆dce ? justify your answer below.

show your work

Yes it is congruent

Step-by-step explanation:

1) if you reflect DCE it would fit perfectly on top of ABC

2) A and D both have a dash

B and c both have a dash

C is in the middle of them both

showing they are both the same

It is indeed congruent.

Step-by-step explanation:

If DCE is reflected you will see that it is the exact same as ABC

Both triangles have dashes on each side reflecting each other

The C is in the middle representing that the two triangles are identical.

I hope this helped! Good luck on whatever test you are taking!! :)))

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
