I will fan and give a medal to anyone who can help please!! Urgent!-If parallelogram ABCD (coordinates: -4,1 -3,2 0,2 -1,1) was reflect…

OpenStudy (templeguy):

its (-4,1)

OpenStudy (templeguy):

I sent you a message

OpenStudy (mndean):

@templeguy what does that have to do with my question?

OpenStudy (seratul):

mndean, did you write the entire question? I think you forgot some key words.

OpenStudy (templeguy):

I answered the question

OpenStudy (seratul):

Is the parallelogram reflected over the y or x axis?

OpenStudy (seratul):

@templeguy There is no way you could've gotten the answer if it doesn't say which was the parallelogram is reflected.

OpenStudy (mndean):

@Seratul here's the full question: If parallelogram ABCD was reflected over the y-axis, reflected over the x-axis,and rotated 180°, where would point A' lie? [Hint: Place your coordinates in the blank with no parentheses and a space after the comma in the form: x, y.] (5 points)

OpenStudy (mndean):

@Seratul and the coordinates for ABCD are: (-4,1) (-3,2) (0,2) (-1,1)

OpenStudy (mathmate):

Start with cutting a scalene triangle and do the same reflections, about x-axis, then about y-axis, then rotate 180 degrees, (all on a piece of paper) and see what you actually get. You may be pleasantly surprised. In terms of transformations, \(s_{x}: (x,y)->(x,-y)\) \(s_{y}: (x,y)->(-x,y)\) \(r_{180}: (x,y)->(-x,-y)\) So \(r_{180}\circ s_{y}\circ s_{x} (x,y)\rightarrow (x,-y)\rightarrow (-x,-y)\rightarrow (x,y)\)

OpenStudy (mndean):

@mathmate I reflected it over the y axis and over the x-axis, but I can't figure out how to rotate it 180 degrees.

OpenStudy (mathmate):

\(r_{180}: (x,y)->(-x,-y)\) it means negate both the x and y coordinates.
