- campbell_st

find angle BAD by angle sum of a triangle
then angle BCD = angle BAD opposite angles in a parallelogram are equal

- anonymous

so 34 or..?

- MrNood

in triangle BAD the 3 angle add up to 180
You know 2 of them - so you can work out

- anonymous

64?.. I think.

- MrNood

what is 83 + 34?
then the 3rd angle make that add up to 180
(not 64)

- anonymous

113?

- 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

\[83+34 \neq 113\]

- UsukiDoll

think of it as one of those solve for x problems
83+34 + x = 180

- UsukiDoll

now you need to solve 83+34 first

- anonymous

117.

- UsukiDoll

117+x=180

- anonymous

So 117 - 180 should give me my answer, right?

- anonymous

63?

- UsukiDoll

x = 180-117
there solve that

- anonymous

63, no?

- UsukiDoll

yes it's 63

- UsukiDoll

83 +34+ 63 all add up to 180

- UsukiDoll

so your

Alright, thank you! Okay, this one has been stumping me for a while now...

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)

- anonymous

I think it's A, but I am not sure.

- UsukiDoll

graph those on a piece of paper and then compare it to a real parallelogram

- anonymous

I failed, and I will try again tomorrow, but for now, I need sleep. Gute Nacht alles.
