Given: segment ac is perpendicular to segment bd prove: δacb ~ δecd reflect δecd over segment ac. this establishes that ∠acb ≅ ∠e'c'd'. then, this establishes that therefore, δacb ~ δecd by the aa similarity postulate. translate point e' to point a; ∠e'd'c' ≅ ∠abc translate point d' to point a; ∠e'd'c' ≅ ∠bac translate point d' to point b; ∠d'e'c' ≅ ∠bac translate point e' to point a; ∠d'e'c' ≅ ∠bac

answer

a the answer hopes this

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

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

answer: you need to organize this better it does not make sense.
