Question

I need help solving this puzzle. You connect the thereom to the Letter 39-43

Answer 1

39. If 4a = 5b and 5b = 7c, then 4a = 7c

`\Rightarrow Transitive\text{ theorem}`

40. If m∠1 = 25, then m∠1 + 65 = 25 + 65

`\Rightarrow Addition\text{ prop. of}`

41. If m∠1 + m∠2 =90, then ∠1 and ∠1 are complementary.

42. If ∠5 and ∠7 are supplementary and ∠7 and ∠2 are supplementary, ∠5 ≅ ∠2

`\Rightarrow Supplements\text{ theorem}`

43. If ∠1 and ∠3 form a linear pair, then ∠1 and ∠3 are supplementary angles.

`\Rightarrow Linear\text{ Pair Theorem}`
