Question 571359: Hello there! This is a question I had on a test review worksheet, that i didn't quite understand.
"Quadrilateral ABCD is a parallelogram. If adjacent angles are congruent, which statement must be true?"
A: Quadrilateral ABCD is a square
B: Quadrilateral ABCD is a rhombus
C: Quadrilateral ABCD is a rectangle
D: Quadrilateral ABCD is an isosceles trapezoid
I have eliminated "B" and "D", but I am unsure as to whether ABCD is square or rectangle. Could you kindly explain as to why it is either one?

Question 565817: my homework is asking me: For what values of x and y must each figure be a parallelogram?
1. it is a rhombus with 4y , x , 2y, and (5x-180) in each corner. (angle measures)
i tried to create a problem by doing 6y+6x-180=180 but it didn't work out and i don't know any other way to do it. can you please help thank you :)

Question 556153: Qhen finding the measure of the interior angle and finding X how do you find
J,K,L,M If J=(3x-6) K=(x+10) L=2x and M=(2x-8)?
i used the equation-n-2(180) add up all my x's and numbers and got 8x-4=360
+4 +4 and got 8x=364 then divided that by 8 to get X=44.5

Question 555967: The questions asks:
What is the most precise classification of this quadrilateral which has opposite sides with equal slopes and consecutive sides with slopes that are negative reciprocals?
I have tried to graph things that would work and thought of the descriptions of the geometric shapes, but I just can't seem to find one that fits this description.

Question 555191: My question is:
Graph the point A(3,2), B(1,-2), C(2, -5), D(4,-1) on the coordinate plane. What kind of quadrilateral is ABCD? Use math to justify your answer.
I did the graph and it looks like a parrallelagram, but I do not know how to justify this if it is correct.

Question 554341: Suppose two distinct parallelograms lie in a plane. What is the LARGEST number of points at which they can intersect?
The answer choices are: 2, 4, 6, & 8.
I was thinking it was either 2 or 4, but I just can't remember. I've looked everywhere in my notes, and Google is kind of useless :(
Thank you!!

Question 545533: in rhombus ABCD, the measure of angle A and the measure of angle B are in the ratio 2:1, AB= 2x+8, BC= 5x+10.
i dont know what to do. i tried drawing it on a piece of paper but I dont know what im suposed to do.
