I am in Geometry and need some help with it, but I have the answers on some, but not for sure if they are right and need someone to check them. Attachments will be posted in the comments. Medal will be rewarded for the help! :D

Tell me if I am on the right track and answer MUST be correct and accurate!!!!!

i have no idea about the first one maybe you need the double arrow

4 years ago
OpenStudy (firejay5):

Are you good at Geometry?

4 years ago
OpenStudy (anonymous):

no

4 years ago
OpenStudy (anonymous):

you might want to say "line LM is parallel to line PR" for the second one

4 years ago
OpenStudy (firejay5):

Line MQ is perpendicular

4 years ago
OpenStudy (anonymous):

yes and the third one looks good

4 years ago
OpenStudy (anonymous):

complimentary means they add up to 90 degrees or make a right angle

4 years ago
OpenStudy (firejay5):

Line LN and PR are parallel to each other and MQ is perpendicular to line LN & PR

4 years ago
OpenStudy (anonymous):

yes

4 years ago
OpenStudy (firejay5):

Is 1. A

4 years ago
OpenStudy (anonymous):

no i think it is the oe with the double arrow, but don't take my word for it

4 years ago
OpenStudy (firejay5):

It is, but which one C or D

4 years ago
OpenStudy (anonymous):

C doesnt have a double arrow, only D does

4 years ago
OpenStudy (firejay5):

It's either A or D

4 years ago
OpenStudy (noelgreco):

#1 : it is a line, not a ray or segment, so the arrow has to be double-ended. A line is defined by two points.

4 years ago
OpenStudy (firejay5):

I got that and put D

4 years ago
OpenStudy (firejay5):

Cause it can't be A because the name won't make sense

4 years ago
OpenStudy (noelgreco):

It can't be A because there exist an infinite # of lines that go through point G

4 years ago
OpenStudy (firejay5):

so was I right with D

4 years ago
OpenStudy (noelgreco):

Yes.

4 years ago
OpenStudy (firejay5):

For #2A. I put, "Line LN is Parallel to Line PR. 2B. Line MQ is Perp. with Line LN & PR. Is that right?

4 years ago
OpenStudy (noelgreco):

Yes.

4 years ago
OpenStudy (firejay5):

Is that correct? You're positive

4 years ago
OpenStudy (noelgreco):

Would I kid you? I'm a retired math teacher.

4 years ago
OpenStudy (firejay5):

Oh well I didn't know

4 years ago
OpenStudy (firejay5):

For 3A. I put measure angle PUQ = 25 degrees. Is that right or is it QUP?

4 years ago
OpenStudy (noelgreco):

Your answer to # 3 is correct. Yes, I'm sure.

4 years ago
OpenStudy (firejay5):

Another person put QUP and not for sure if it matters or not

4 years ago
OpenStudy (noelgreco):

Vertical angles are congruent. Thanks for not just asking for the answers. Memorize your theorems.

4 years ago
OpenStudy (firejay5):

So if I would put QUP is that wrong?

4 years ago
OpenStudy (noelgreco):

QUP is fine.

4 years ago
OpenStudy (firejay5):

Cause it seems both make sense

4 years ago
OpenStudy (noelgreco):

Don't over-think it.

@NoelGreco What about 3B & 3C

4 years ago

Going to dinner.

OpenStudy (firejay5):

@kropot72 What's 3B & 3C

4 years ago
OpenStudy (anonymous):

Do u still need help

4 years ago
OpenStudy (firejay5):

@*STAR* Just to be checked. 3B I have measure angle PUQ & QUR. 3C I put measure PUQ & RUS

4 years ago
OpenStudy (firejay5):

Is it right? @*STAR*

4 years ago
OpenStudy (anonymous):

is that all that you could figure out yourself

4 years ago
OpenStudy (firejay5):

yes, but I don't know if it's right?

4 years ago
OpenStudy (firejay5):

@phi Is this #3B & C right?: 3B I have measure angle PUQ & QUR. 3C I put measure PUQ & RUS

4 years ago
OpenStudy (phi):

complementary angles add up to 90º so < PUQ and < QUR are complementary supplementary add to 180 degrees and PUQ + RUS = 180 Yes, your answers look good

4 years ago
OpenStudy (mathstudent55):

<PUQ and <RUS are not supplementary. m<PUQ = 25; m<RUS = 90 m<PUQ + m<RUS = 25 + 90 = 115 <PUQ and <QUS are supplementary. m<PUQ = 25; m<QUS = 65 + 90 = 155 m<PUQ + m<QUS = 25 + 155 = 180

@phi What would be the correct answer to 3A

4 years ago
OpenStudy (phi):

you did 3a correctly

4 years ago
OpenStudy (mathstudent55):

<QUP or <PUQ are both correct answers to 3A because they are both correct ways of naming that angle.

4 years ago
OpenStudy (firejay5):

I put QUP is that also correct answer

4 years ago
OpenStudy (mathstudent55):

Read my comment just above your last comment. Yes, it's correct.

4 years ago
OpenStudy (firejay5):

@mathstudent55 Can Q be used more than once

4 years ago
OpenStudy (mathstudent55):

It can be used to name many angles, lines, segments and rays. Do you have a specific question about Q?

4 years ago
OpenStudy (firejay5):

Well I thought you couldn't do that, but I stood correct

4 years ago
OpenStudy (firejay5):

Is 3B. PUQ & QUR

4 years ago
OpenStudy (mathstudent55):

Yes. <PUQ and <QUR anr complementary. There is an angle symbol that should be used when you are dealing with angles.

4 years ago
OpenStudy (mathstudent55):

Concerning your question about using Q more than once, I still am not sure what you mean, but as you can see, your answer to 3B does use Q in the names of two different angles, and that answer is correct.

4 years ago
OpenStudy (firejay5):

This is the Answer to 2A & B: Line LN and PR are parallel to each other and MQ is perpendicular to line LN & PR

4 years ago
OpenStudy (mathstudent55):

Correct.

OpenStudy (firejay5):

I got it right omg I accomplished something

4 years ago
OpenStudy (mathstudent55):

Great. OS does work!

4 years ago
OpenStudy (firejay5):

and then 1 I put D.

4 years ago
OpenStudy (firejay5):

is that right too?

4 years ago
OpenStudy (mathstudent55):

Correct. There are two ways of naming a line. 1. One way is simply a small letter that names the entire line. 2. The other way is to use any two points on the line. When you write the name of the line using the second method, you write two capital letters for the names of the two points, and a small line symbol above the two letters. The small line symbol is a little horizontal segment with an arrowhead pointing in each direction.

4 years ago
OpenStudy (mathstudent55):

Line m can be named only one way since we don't have any named points on line m. Line t can be named in 7 different ways since there are three named points on line t. Any of these 7 names is a correct name for line t. |dw:1377219378171:dw|
