OpenStudy (itrymath):

whats the difference between all the angles in number 1,2...? like complimentary , adjutant etc...?

OpenStudy (itrymath):

adjacent

OpenStudy (itrymath):

@3mar

OpenStudy (itrymath):

@Seratul

OpenStudy (3mar):

Well, I am here.

OpenStudy (itrymath):

do you know my question?

OpenStudy (3mar):

in the PDF,, right?

OpenStudy (itrymath):

yes, equation 1

OpenStudy (3mar):

I see now... So Where are you stuck?

OpenStudy (itrymath):

angle's, what are the diff between them?

OpenStudy (3mar):

Between 4 and 5 only or between all of them?

OpenStudy (itrymath):

between all and 4 and 5

OpenStudy (3mar):

1 and 2 and 3: form what type of angle?|dw:1482105851884:dw|

OpenStudy (itrymath):

supplementary

OpenStudy (3mar):

\[\checkmark\] as they form a straight line (180 degrees)

OpenStudy (3mar):

and the same with 4 and 5?? |dw:1482106010846:dw|

OpenStudy (itrymath):

yes

OpenStudy (itrymath):

but 4 and 5 are linear pairs

OpenStudy (3mar):

and what is the wrong with that?

OpenStudy (itrymath):

linear pair means supplementary ?

OpenStudy (itrymath):

oh okay yes it does

OpenStudy (itrymath):

so number 2 would be C, correct?

OpenStudy (itrymath):

@3mar

OpenStudy (3mar):

Yes, as their measures add up to 180

OpenStudy (itrymath):

it says the answer is D

OpenStudy (3mar):

"Yes, as their measures add up to 180" I was talking about 1 sorry

OpenStudy (3mar):

So you just need check of 2?

OpenStudy (itrymath):

but you said if its 180 then its supplementery

OpenStudy (3mar):

Yes, that is for 4 and 5 when you said "Linear Pairs"...

OpenStudy (itrymath):

im on number 2

OpenStudy (3mar):

\[\Huge \angle \color{blue}{ABC}=~~?\]

OpenStudy (itrymath):

OpenStudy (3mar):

I know the question, friend! I ask you to see if you recognize that angle as a straight angle or not!

OpenStudy (itrymath):

no they are acute

OpenStudy (3mar):

angle ABC is an acute angle??

OpenStudy (itrymath):

no supplementery

OpenStudy (itrymath):

hello? @3mar

OpenStudy (itrymath):

@sshayer

OpenStudy (itrymath):

number of the pdf

OpenStudy (itrymath):

number 2 **

OpenStudy (sshayer):

<1+<2+<3+<4=180 <2+<3=90 <1+<4+90=180 <1+<4=180-90=90 so angles 1 and 4 are complementry

OpenStudy (itrymath):

what is the degree's for a complimentary angle ?

OpenStudy (sshayer):

angles are complementry if sum of two angles =90 degree

OpenStudy (itrymath):

oh so i would just have to add whatever angles they told me for example <2 and <3 and I add those and i get 90.... so what would it be complimentary

OpenStudy (sshayer):

<2 and <3 complementry if <2+<3=90 but it is given <DBF is aright angle. so <2 and <3 are complementry

OpenStudy (3mar):

Keep that in mind: How to remember which is which? Easy! Think: "C" of Complementary stands for "Corner" right angle(a Right Angle), and "S" of Supplementary stands for "Straight" (180 degrees is a straight line)
