What needs to be corrected in this construction of a line parallel to ab passing through c?
second arc (centered
arst arc (centered at d)
a. the first art should pass through
b. the testare should be centered at
c. the second he should be centered ac
d. the second are should cross the last c.
e the second and should be contated at

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
