A(0,4)b(2,2) and c(-2,-1) Which expression represents the perimeter of the triangle

Option B

Step-by-step explanation:

A(0,4) & B(2,2)

B(2,2)  & C(-2,-1)

A(0,4) ; C(-2,-1)

Perimeter of triangle = AB + BC + AC

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
