Mrs. Beno wrote this equation on the board and asked, "Is this a true equation?" \left(x+y\right)^2=x^2+y^2(x+y) 2 =x 2 +y 2 Nigel said sometimes it is and sometimes it is not and broke the equation into 4 cases. For each case determine whether the equation is true or false and explain your reasoning.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
