Please help me with this I don't have much time...

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

source:

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this
