Use the number line to complete the statements. The length of JK is units. For a ratio of 1:2, divide the length of JK into equal parts. The point that divides JK in a 1:2 ratio is 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

central angle of a triangle has the same measure as its intercepted arc.
