Question

Need help completing this proof on triangles

Answer 1

@khusker I need to know some letters that were cut off the diagram. Thanks.

Answer 2

sorry far right part missing is W

Answer 3

Okay, thanks.

Answer 4

1. is given ,
2. conclusion this angles equals because the 2 parallel line (this not given)

Answer 5

3.is given ,you can see in the line where written GIVEN

Answer 6

4. similar to 2;

Answer 7

I see #3 - that was obvious - thanks

Answer 8

I have to state the postulates or theromes for 2, 4 & 6 any ideas?

Answer 9

I finally see 1, 3, & 5 are given thanks for that :)

Answer 10

Directx how you choose Theorem or Axiom

Answer 11

or postulates

Answer 12

I can't read 2 & 4

Answer 13

See what you think.

Some texts take the statement "If 2 parallel lines are cut by a transversal, then corresponding angles are congruent" as a postulate and prove the other pairs of congruent angles from them.

Answer 14

I have not encountered anyone on OS who did not take Corresponding Angles as a postulate.

Answer 15

there is 2 answers ? theorem and postulate

Answer 16

I don't know what you mean by that.

Answer 17

2 and 4 read "corresonding angles postulate"

Answer 18

I'm suppose to state these like the attachment

Answer 19

@khusker will need to look in his text to determine whether the Corresponding Angles Postulate was taken as a theorem.

Answer 20

Here it is: Corresponding Angles Postulate

Answer 21

got it thanks!! Thanks Directrix!!

Answer 22

You are welcome.

Answer 23

Really cool that you could share that list of postulates and theorems. That will help me as I help others with their proofs. Thanks. @khusker

Answer 24

Directrix... Glad I could help you somehow. The teacher makes us use that on everything
