The proves that ∆abc and ∆efg are congruent by the sas criterion.
a. angle a is congruent to angle e
b. b is congruent to angle f
c. ab=ef
d. angle c is congruent to angle g
if ab ≠ ef, criterion for congruency is violated
a. ssa
b. asa
c. sss
d. sas
in this situation, angle c g.
a.may be congruent to
b.is congruent to
c.cannot be congruent to

I believe that the best answer among the choices provided by the question are:

A. Angle A is congruent to angle EA. SSA
C.Cannot be congruent to

Hope my answer would be a great help for you.    If you have more questions feel free to ask here at .

The condition  angle A is congruent to angle E proves that ∆ABC and ∆EFG are congruent by the SAS criterion.

If AB ≠ EF, the  SSA criterion for congruency is violated.

In this situation, angle C  cannot be congruent to angle G.

Step-by-step explanation:

A) The first 4 terms of the sequences are: , , and .

B) An explicit formula for this sequence can be written as:

C) A recursive formula for this sequence can be written as:

Step-by-step explanation:

A) You can find the firs terms of this sequence simply selecting an odd integer and summing the consecutive 3 ones:

(a.1)

B) Observe the sequence of odd numbers 1, 3, 5, 7, 9, 11, 13(...).

You can express this sequence as:

(b.1)

If you merge the expression b.1 in a.1, you obtain the explicit formula of the sequence:

(a.1)

(b.2)

(b.3)

(b.s)

C) The recursive formula has to be written considering an initial term and an N term linked with the previous term. You can see an addition of 8 between a term and the next one. So you can express each term as an addition of 8 with the previous one. Therefore, if the first term is 16:

(c.s)
