seppy ready for torture ;-; ? should i post the problem/
need help with all ;-;
hmm should i draw it? might be helpful
|dw:1436674860165:dw|Notice that <3 and <6 are VERTICAL ANGLES. What's special about vertical angles?
they cross or intersect?
no... you gotta remember your basic geometry stuff -_- important for problems like this vertical angles are always equal
so if <3=30 then <6=30 because <3 and <6 are vertical angles
right its that easy?
ya :U most of them will be similar i think
|dw:1436675341585:dw|I dunno why they're doing this counterclockwise, kinda sloppy. but ok.. here is our angle :)
|dw:1436675406493:dw|The instructions told us that BHG is a right angle, 90 degrees.
How much do we have `left over` for our angle 6?
we started with 115. and we used up 90 how much left over? 0_o
do you have a calculator handy that you can use? :\
ok good. so angle 6 = 25 degrees. what does that tell us about angle 3? `think back to the previous question`
its that same as <6
good good good :D so we've determined that angle 3 = 25
Again we'll need to look back at the directions and see which right angles were given.
|dw:1436675812601:dw|So this shows us that <6 + <7 = 90
|dw:1436675837783:dw|This shows us that <1 + <7 = 90
6 + something = 90 1 + that same thing = same amount
so whats going on with 6 and 1?
@pooja195 maf time pats? :D
._. i guess so.
this is all so confusing ._.
u left .-.
o sorry usuki was making fill out some survey -_-
What are we working on? same questions?
LOL ik what that survey was xD and i dont get any of this
ok here is some practice :d
What is special about angles 1, 2 and 3?
They are vertical ?
no. All three of them together form half a circle, see that? See the straight line underneath?|dw:1437020540856:dw|
a whole circle is 360 degrees. so these three angles form half of that. <1 + <2 + <3 = 180 degrees.
I dunno if you've done much half-circle stuff yet. whatev
How bout this on|dw:1437020601346:dw|e,
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?
that its 90 degrees?
|dw:1437020781547:dw|woops lemme give letters to these other angles.
