find angle BAD by angle sum of a triangle then angle BCD = angle BAD opposite angles in a parallelogram are equal
anonymous
  • anonymous
so 34 or..?
MrNood
  • MrNood
in triangle BAD the 3 angle add up to 180 You know 2 of them - so you can work out
anonymous
  • anonymous
64?.. I think.
MrNood
  • MrNood
what is 83 + 34? then the 3rd angle make that add up to 180 (not 64)
anonymous
  • anonymous
113?
MrNood
  • MrNood
does 83+34 + 113 = 180? if not then that is not the right answer 83+ 34 + ? = 180
anonymous

I don't understand. This is like Algebra, no?
UsukiDoll
  • UsukiDoll
\[83+34 \neq 113\]
UsukiDoll
  • UsukiDoll
think of it as one of those solve for x problems 83+34 + x = 180
UsukiDoll
  • UsukiDoll
now you need to solve 83+34 first
anonymous

117.
UsukiDoll
  • UsukiDoll
117+x=180
anonymous
  • anonymous
So 117 - 180 should give me my answer, right?
anonymous
  • anonymous
63?
UsukiDoll
  • UsukiDoll
x = 180-117 there solve that
anonymous
  • anonymous
63, no?
UsukiDoll
  • UsukiDoll
yes it's 63
UsukiDoll
  • UsukiDoll
83 +34+ 63 all add up to 180
UsukiDoll
  • UsukiDoll
so your

Which set of vertices forms a parallelogram? A) A(2, 4), B(3, 3), C(6, 4), D(5, 6) B) A(-1, 1), B(2, 2), C(5, 1), D(4, 1) C) A(-5, -2), B(-3, 3), C(3, 5), D(1, 0) D) A(-1, 2), B(1, 3), C(5, 3), D(1, 1)

I think it's A, but I am not sure.
UsukiDoll
  • UsukiDoll
graph those on a piece of paper and then compare it to a real parallelogram
