ℜ0, -180 is the same rotation as

a. ℜ 0, 180
b. ℜ -90, 180
c. ℜ 90, 180
d. ℜ 0, 90

option A) 0,180

Step-by-step explanation:

Given that there is a rotation of 0,-180. That is x is not rotated but y is rotated exactly 180 degrees clockwise.

A rotation is a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a particular point sometimes origin.

Counterclockwise rotations are positive while clockwise rotations are negative.

WE know that 180 degrees clockwise and 180 degrees anticlockwise would give the same result as total angle around a point is 360 degrees.

Hence correct answer is option A) 0,180

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

answer:

a=9
