Angle Puzzler?

OpenStudy (anonymous):

OpenStudy (anonymous):

All the blue numbers are irrelevant

OpenStudy (anonymous):

So ignore them, the red numbers are given angles

OpenStudy (anonymous):

and the black ones are the ones I filled in

OpenStudy (unklerhaukus):

are you looking for a particular angle, or all of the angles?

OpenStudy (anonymous):

All the angles with blue numbers is what I need.

OpenStudy (unklerhaukus):

you can find number 6 with supplementary angles

OpenStudy (anonymous):

Ah yes, that would be 50!

OpenStudy (anonymous):

Then the angle below it is 50 too

OpenStudy (anonymous):

I put a little more stuff in. I can't find anything else at the moment XP

OpenStudy (unklerhaukus):

are those two verticals parallel?

OpenStudy (anonymous):

Oh, yeah here's the info: lines a and b are parallel. lines c and d are parallel. line d is perpendicular to e line .

OpenStudy (unklerhaukus):

ah, so at point D there are four right angles

OpenStudy (unklerhaukus):

angle 4 has a complement

OpenStudy (anonymous):

so 4 would be 30!

OpenStudy (unklerhaukus):

yes

OpenStudy (anonymous):

OpenStudy (unklerhaukus):

angle 7 corresponds with something

OpenStudy (anonymous):

Angle 6?

OpenStudy (unklerhaukus):

not quite

OpenStudy (anonymous):

I think its one in that triangle

OpenStudy (anonymous):

Maybe where point D is?

OpenStudy (unklerhaukus):

|dw:1384959060965:dw|

OpenStudy (anonymous):

With 4!

OpenStudy (unklerhaukus):

almost

OpenStudy (anonymous):

Yes

OpenStudy (unklerhaukus):

|dw:1384959221577:dw|

OpenStudy (anonymous):

Ohhh. Got it XD

OpenStudy (anonymous):

12 more to go! XD

OpenStudy (unklerhaukus):

if we look at the lines a and b (which are parallel). can you see an alternate angle?

OpenStudy (anonymous):

Where point J and H are

OpenStudy (unklerhaukus):

Yes thats right

OpenStudy (anonymous):

Oh so 5 would be 70!

OpenStudy (unklerhaukus):

thats it!

OpenStudy (anonymous):

Got it XD

OpenStudy (unklerhaukus):

good stuff, now angle 11 can be found, using ' the sum of angles in a triangle is 180°

OpenStudy (anonymous):

45 degrees?
