Help please 8. If a triangle has sides that are 5, 12 and 13, is it a right triangle?

A. No because 12 + 13 > 5

B. No because 5 + 12 ≠ 13

C. Yes because 5 + 12 > 13

D. Yes because 132 - 122 = 52

c

step-by-step explanation:

c

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
