The tallest tree in the forest is 150 feet from the water tower. unfortunatly in a lightning storm the tallest tree was struck and caught on fire. the ranger needs to go from his tower to the water tower to get the water to put out the fire. how far is it from the rangers tower to the water tower

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
