Tutors Answer Your Questions about Parallelograms (FREE)
Question 112915: Find the value of each variable that will allow you to prove that ABCD is a parallelogram. Then find the measure of each angle of the parallelogram. Angle B is (2x-3y) degrees: angle C is (x+y) degrees; angle D is (5x-y) degrees. Angle A is blank but A is opposite of angle C on the parallelogram and angle B is opposite angle D. Please help. Thanks.

Question 113923: Hi. How would I use the distance, midpoint and slope formula to find where a point should go to make a parallelogram? Because on this homework it shows point A(7,12) B(15,4) C(9,2) D(3,5) The question is to move Point B so that it makes a parallelogram. How would I know where to move it? Thank You for your help!

Question 115500: find the value of x and y in the parallelogram PQRS
the diagonals of the parallelogram are QS and RP,and they bisect at point T. QT=3x, RT=y+3, PT=2x, and ST=2y
I have done number 18, and I have been working on this one for probably half an hour. I just don't know how to get the answer from the information given.
Thank you!

Question 117362: well, its not really from the book but i just hope that someone could help me anyway. it is off a study guid for school for a semester test. There is a Trapezoid and the measure of angle A= 90 degrees.the measure of angle C= 50 degrees. the measure of angle D= 90, and find the measure of angle B? that is the best way that i can explain it because there is a picture that goes with it and i cant get it on the computer.

Question 118474: these are the corrdinates of three points (0,10),(30,10),(20,-30)
find a fourth point so that the four points form the vertices of a parallelogram.
how would you do this? how many different points could be the fourth vertex?what are the coordinates of these points? write your answers below. show the different possible parallelograms in different colors on the grid.

Question 121766: Use the concept of slope to determine if the given figure is a parallelogram or a rectangle.
I do not understand how to determine this. I have a picture but I cannot paste it here. Can you help me with understanding the concept?

Question 127876: We just started a lesson about rectangles and parallelograms. The question I need your help with is how do I draw and label a figure with A = 64 cm squared and P = 64 cm? Since the question uses the term "figure", I guess it could be ANY type of figure, but since the lesson is about rectangles and parallelograms, I guess it is one of those. I know that the parallelogram A = b x h and that the P = (2 x b) + (2 x h). I also know that if the "figure" I am looking for is a parallelogram, then b x h = 64 cm squared and that (2 x b) + (2 x h) = 64 cm. I tried to solve for one variable in one equation and substitute that in the other equation but I keep getting stuck with the 64 cm in one equation and 64 cm squared in the other equation. Can you please help me solve this? My teacher gave our class a hint that we should consider fractions in our solution, but I don't know how to use this hint! Thanks.

Question 135553: Theres a parallelogram slanted to the right. (SRQP) M is in between SR and connects to the bottom right angle, angle Q, making MQ. T is in between PQ and connects up to the top left angle, angle S. So the top of the shape is SMR, and the bottom is PTQ. Given: PQRS is a parallelagram and PT is congruent to RM. Prove TQMS is a parallelagram. by the way, the book is called course 2, integrated mathematics, 3rd edition. chapter 7, page 268, this one os problem 11 but if anyone knows problems 11-13 and 15 you would be awesomeeee=]
thankss.
PLEASE HELPPPP!!!

Question 135980: I am trying to establish the correct equation for
The points (1,5), (4,5), and (1,0) represent three corners of a rectangle; find the coordinates of the fourth point.
For obvious reasons I concluded that the fourth point is (4,0), but I am unsure how to present this.
m = y4 - y3 – y2 – y1/x4 - x3 – x2 – x1
m = 5 – 5 – 0 – 5/1 – 4 – 1 – 4
Thanks!

Question 137375: I am having difficulty with this. The book doesn't give an exact example on how to solve it, I was wondering if I could get help with it. I did try to solve it, failed.
It asks: The perimeter of []JKLM is 52cm, and Jk is 2cm longer than JM.
Find JK and find JM
Please help, Thank You=)
