|dw:1436674860165:dw|Notice that <3 and <6 are VERTICAL ANGLES. What's special about vertical angles?
pooja195
  • pooja195
they cross or intersect?
zepdrix
  • zepdrix
no... you gotta remember your basic geometry stuff -_- important for problems like this vertical angles are always equal
zepdrix
  • zepdrix
so if <3=30 then <6=30 because <3 and <6 are vertical angles
pooja195
  • pooja195
right its that easy?
zepdrix
  • zepdrix
ya :U most of them will be similar i think
zepdrix
  • zepdrix
|dw:1436675341585:dw|I dunno why they're doing this counterclockwise, kinda sloppy. but ok.. here is our angle :)
zepdrix
  • zepdrix
|dw:1436675406493:dw|The instructions told us that BHG is a right angle, 90 degrees.

  • zepdrix
How much do we have `left over` for our angle 6?
pooja195
  • pooja195
27 degees?
zepdrix
  • zepdrix
we started with 115. and we used up 90 how much left over? 0_o
pooja195
  • pooja195
26 .-.
zepdrix
  • zepdrix
do you have a calculator handy that you can use? :\
pooja195
  • pooja195
25
zepdrix
  • zepdrix
ok good. so angle 6 = 25 degrees. what does that tell us about angle 3? `think back to the previous question`
pooja195
  • pooja195
its that same as <6
zepdrix
  • zepdrix
good good good :D so we've determined that angle 3 = 25
zepdrix
  • zepdrix
|dw:1436675761963:dw|

  • zepdrix
Again we'll need to look back at the directions and see which right angles were given.
zepdrix
  • zepdrix
|dw:1436675812601:dw|So this shows us that <6 + <7 = 90
zepdrix
  • zepdrix
|dw:1436675837783:dw|This shows us that <1 + <7 = 90
zepdrix
  • zepdrix
6 + something = 90 1 + that same thing = same amount
zepdrix
  • zepdrix
so whats going on with 6 and 1?

@pooja195 maf time pats? :D
pooja195
  • pooja195
._. i guess so.
pooja195
  • pooja195
this is all so confusing ._.
pooja195
  • pooja195
u left .-.
zepdrix
  • zepdrix
o sorry usuki was making fill out some survey -_-
zepdrix
  • zepdrix
What are we working on? same questions?
pooja195
  • pooja195
LOL ik what that survey was xD and i dont get any of this
zepdrix
  • zepdrix
ok here is some practice :d

What is special about angles 1, 2 and 3?
pooja195
  • pooja195
They are vertical ?
zepdrix
  • zepdrix
no. All three of them together form half a circle, see that? See the straight line underneath?|dw:1437020540856:dw|
zepdrix
  • zepdrix
a whole circle is 360 degrees. so these three angles form half of that. <1 + <2 + <3 = 180 degrees.
zepdrix
  • zepdrix
I dunno if you've done much half-circle stuff yet. whatev
zepdrix
  • zepdrix
How bout this on|dw:1437020601346:dw|e,
zepdrix
  • zepdrix
so the square on an angle tells us that it's 90 degrees, ya? So the bottom two angles are 90 degrees. What can we say about angle A?
pooja195
  • pooja195
that its 90 degrees?
zepdrix
  • zepdrix
|dw:1437020781547:dw|woops lemme give letters to these other angles.
