What theorem can be used to probe the 2 triangles similar?

B. SAS

Step-by-step explanation:

Two sides of ∆DEF (DE and DF) are proportional to two corresponding sides of ∆ABC (AB and AC), and also their included angles (<D and <A) are equal to each other.

Therefore, based on the SAS criterion, both triangles are proven to be similar to each other.

Both triangles satisfy the SAD Criterion, and hence, they can be proven to be similar to each other.

answer: 40.95

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
