Please assist with this 2 column proof

  use the symmetric and transitive properties of congruence

Step-by-step explanation:

(1) ∠ABC ≅ ∠DEF and ∠GHI ≅ ∠DEF; given

(2) ∠DEF ≅ ∠GHI; symmetric property of congruence

(3) ∠ABC ≅ ∠GHI; transitive property of congruence (QED)

Additional comment

The transitive property says if A≅B and B≅C, then A≅C. We used the symmetric property to swap sides of the congruence symbol with DEF and GHI to put the statement in the form to match the transitive property.

You will note we used the form ...

  (statement number) statement; reason

with statement and reason separated by a semicolon.

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.
