Which set of numbers could be the length of the sides of a triangle? {6, 9, 15}
{3, 3 ,7}
{6, 9, 12}
{1, 2, 3}

the answer would be 3,3,7

Step-by-step explanation:

because to of the sides will be the same and one will be different

Step-by-step explanation:

{3,3,7}

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
