Ahh that’s very very very very swag
Step-by-step explanation:
If ∠1 and ∠2 are supplementary, then m∠1 + m∠2 = 180° (1).
If ∠2 and ∠3 are supplementary, then m∠2 + m∠3 = 180° (2).
From (1) we have
m∠1 + m∠2 = 180° /<em>subtract m∠1 from both sides</em>
m∠2 = 180° - m∠1
<em>substitute it to </em><em>(2)</em>
(180° - m∠1) + m∠3 = 180°
180° - m∠1 + m∠3 = 180° <em>/subtract 180° from both sides</em>
- m∠1 + m∠3 = 0 <em>/add m∠1 to both sides</em>
m∠3 = m∠1 ⇒ m∠1 = m∠3 ⇒ ∠1 ≅ ∠3
It’s not that hard all u need to do is when u multiply it just multiply it. For example what’s 2/3x4/3=8/3 and that is just 8/3 but when the denominator is different u just multiply it it’s not that hard
Answer:
Yes, it can. Triangles [in order for them to be one] must equal 180. If you add all of these angles together, since a triangle only has three angles anyway, it equals to 180, so you know it's a triangle.
If this was confusing, I am happy to help further!
