This website is really helpful!

Answer 2

vertical angles are to angles directly opposite each other. Did that help?

Answer 3

@Im still confused @brainzonly

Answer 4

@brainzonly I understand the concept but I dont understand the answers to my question

Answer 5

Check this out: https://www.khanacademy.org/math/cc-seventh-grade-math/cc-7th-geometry/cc-7th-angles/v/angles-at-the-intersection-of-two-lines

Might help.... =)

Answer 6

Towards the end of the video but you might want to watch it all.

Answer 7

@BlazeRyder can you show me and an example using multiple lines like the one in my question? Thats what is confusing me

Answer 8

Sure, one sec!

Answer 9

Okay, so as you can see all of the points are labeled. And if you can't see it, where all of the points intersect is labeled I. So, Angle AIB & FIE are vertical angles. This is because they are opposite of each other and have the same angle measurement. They also share a vertex. BIC & GIF are vertical angles because they are opposite, probably have the same angle measure and also share a vertex. Does this help you a little bit?

Answer 10

AIH would be considered a vertical angle to right? @blazeryder

Answer 11

Almost. To make your statement above true you have have to add angle DIE. AIH and DIE are vertical angles. Vertical angles come in pairs. There will always be two angles in your answer.

Answer 12

Oh okay now I understand it

Answer 13

Thanks alot!

Answer 14

No problem! I remember having a hard time learning this so I know what you felt like! Have a good day!

Answer 15

@BlazeRyder, from what you told me it seems that only letter B. applies, can you confirm this?

Answer 16

I take that back, Letter D also applies aswell correct?

Answer 17

I would say yes. Both B & D. =)

Answer 18

Thanks! now I know i fully understand, thanks alot @blazeRyder

Answer 19

No problem! Glad I could help!

Answer 20

Could you help with this? @blazeryder

Answer 21

I know one of the answers is B

Answer 22

What do you know about perpendicular lines?

Answer 23

sorry, I was offline. looks like I missed a bit...

Answer 24

I forgot what it means but im gonna search it right now

Answer 25

Let me know when you are done with that =)

Answer 26

two lines which meet at a right angle (90 degrees)

Answer 27

Right! So from the question, what does the little line mean?

Answer 28

Perpendicular

Answer 29

Because the two lines meet to form a right angle correct

Answer 30

Exactly! So we can assume that line AB and XY are perpendicular. Now since the 2 lines are perpendicular we can assume all angle are 90 degrees.

Answer 31

Now what does a supplementary angle and complementary angle mean?

Answer 32

Supplemntary is when 2 angles to 180 complimentary is 90 degrees

Answer 33

Which means they are complimentary

Answer 34

Perfect!

Answer 35

So that means B,C,D are correct?

Answer 36

Close, A and C are saying that if you add these two angles together this is the kind of angle it would form.

Answer 37

At least this is what I think the question implies.

Answer 38

You think so? mabye they meant them as seperate

Answer 39

You could be right on that one...... I would submit it and if you get it wrong, make sure to take note for future questions. As you progress in grade level, they try to trick you!

Answer 40

Right, Im gonna go along with just B and D, its unusual for there to be 3 correct answers on a 4 answer choice question anyways

Answer 41

on apex that is

Answer 42

Ahhhh, my school does that all the time so.....

Answer 43

Yep, thanks for the help! @blazeryder

Answer 44

No problem!
