The two shorter sides of a triangle measure 12 cm and 18 cm. which of the following could be the length of the longest side of the triangle? 1. 30 cm
2. 17 cm
3.27 cm
4. 11 cm​

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

a. is correct
