Question

Complete the paragraph proof.

Given: ∠1 and ∠2 are supplementary, and ∠2 and ∠3 are supplementary.

Prove: ∠1 ≅ ∠3

Angle 1 is acute, angle 2 is obtuse, and angle three is acute.

By definition of supplementary angles, m∠1 + m∠2 = _____ (a) and m∠2 + m∠3 = _____ (b). Then, m∠1 + m∠2 = m∠2 + m∠3 by the __________ (c). Subtract m∠2 from each side. You get m∠1 = ______ (d), or ∠1 ≅ _____ (e).

Answer 1

anyone else cheating

Answer 2

i am unsure but i think that...
A.is 180
B.is 180
C.???
D.is 50
E.is angle 3

Answer 3

i need a response as soon as possible, ms sue? letter C is asking for a property and i think its either substitution or symmetric property. am i correct? if so which one is right? if anyone else knows the answer to this please do let me know

Answer 4

Answer 5

I left it blank. Because Y'all do not be helping nobody understand nothing.

Answer 6

@Leyaah
That is not proper English..

Answer 7

I'm pretty sure that;
a. and b. are both 180 Degrees
c. Transitive
d. and e. are angle 3
I'm not entirely sure though. Can someone check please?

Answer 8

lazra helped alot so if you mess this up its ur fault ur so slow at that point

Answer 9

m∠1 + m∠2 = 180° // definition of supplementary angles
m∠3 + m∠4 = 180° // definition of supplementary angles

m∠1 + m∠2 = m∠3 + m∠4 // transitive property of equality

m∠1 = m∠3 // definition of congruent angles

m∠1 + m∠2 = m∠1 + m∠4 // substitution property of equality (replaced m∠3 with m∠1)

m∠2 = m∠4 // subtraction property of equality (subtracted m∠1 from both sides)

∠2 ≅ ∠4 // definition of congruent angles
