Someone

provide reasons for the statements.
given: ∠1 and ∠3 are vertical angles.
prove: ∠1 ≅ ∠3 .

statement reason
1. ∠1 and ∠3 are vertical angles : given

2. ∠1 and ∠2 form a linear pair.
∠2 and ∠3 form a linear pair.: definition of linear pair

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

4. m∠1 + m∠2 = 180˚
m∠2 + m∠3 = 180˚ :

5. m∠1 + m∠2 = m∠2 + m∠3:

6. m∠1 = m∠3 :

7. ∠1 ≅ ∠3 :

i would say the third one.

step-by-step explanation: liner would mean in a line and the only one that doesn't look like it's even thinking about forming a line would be the third one

1. perpendicular

2. parallel

3. perpendicular

it would be a on edgenuit y

the diagram below is your final answer

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
