Question

Given: C || d
Prove: <1 is supplementary to <2

Answer 1

This is the picture along with this problem

Answer 2

Type of chart I have to use.

Answer 3

Do you about the postulates and theorems for this problem?

Answer 4

I just need help with 2, 3, and 4... I have #1. Thats C || D and its the given.

Answer 5

Well <1 and <3 are supplementary(that's a theorem). <3 and <2 are identical b/c they are vertical angles. Substitute <3 for angle <2 and there you go.

Answer 6

I think for that kind or chart you list the steps on one side and the theorems/postulates on the other side right?

Answer 7

the statements go on one side and then the reasoning goes on the other side. And why would you substitute <3 for <2?

Answer 8

because you're proving <1 is supplementary to <2

Answer 9

So <1 and <3 are supplementary, thats #2? And then <3 and <2 are identical b/c they are vertical angles is #3 amd then #4 is substitute <3 for angle <2?

Answer 10

yes

Answer 11

Your teacher of wherever you got his problem might want you to solve this a different way but this way works

Answer 12

thank you sooo much and could you explain how you figured that out becuase I have to do ones probably similiar or exactly alike on a test sometime this week.

Answer 13

Okay and its on my test review for geometry.

Answer 14

Oh then just ask your teacher later. Geometry's tricky.

Answer 15

Okay but thamks anyways.

Answer 16

no problem
