Question

State the missing proofs from below...

Answer 1

Here is the chart

Answer 2

My answers are

a) Vertical Angles
b) Alternate Interior Angles
c) ?

I'm not sure if I am correct and I am having difficulties on C. i know it is parallel though

Answer 3

a) Vertical Angles = \(\color{green}{\checkmark}\)

Answer 4

b) Alternate Interior Angles - is wrong

Answer 5

alternate interior angles are NOT equal if lines are not parallel

Answer 6

since we dont knw yet if the lines are parallel or not, we cannot use it.

Answer 7

a=b, and b=c

=>

a=c

which property is it ?

Answer 8

Ummm....so bad at geometry but I think it is transversal property???

Answer 9

^right, its "transitive property of equality"

Answer 10

4 = 1, and <1=5

=>

<4=<5

do u see transitive property here ?

Answer 11

my bad! I meant transitive! lol, yes I do see it! So letter B would be Transitive Property?

Answer 12

<4 = <1, and <1=<5

=>

<4=<5

By "transitive property of equality"

Answer 13

Alrighty, Thank you!

Answer 14

so by row 3, we have proved alternate interior angles are congruent

Answer 15

right ?

Answer 16

did u figure out what to put for c) already ha

Answer 17

I haven't figured out c yet, lol.

Answer 18

But that is fine! I'm getting help from one of my family members right now! Thanks for helping me on the rest of it though!

Answer 19
