State weather the triangles are similar .if so write a similarity statement and the postulate theorem you used. the triangles are not drawn to scale

The answer in the procedure

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding interior angles are congruent

so

substitute the values

-----> is true

Therefore

JK is parallel to MN

Triangles OMN and OJK are similar by AA Similarity Postulate ( The three interior angles are congruent)

Because

m<OKJ=m<ONM ----> by corresponding angles

m<KJO=m<NMO -----> by corresponding angles

m<JOK=m<MON -----> is the same angle

step-by-step explanation:

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
