Triangle ABC goes through a series of three transformations, resulting in triangle A^ prime B^ prime C^ prime . The three transformations are listed below. Rotation 180clockwise about the origin • a reflection over the x-axis • reflection over the y- axis Triangle ABC has vertex A located at (2, - 3) . Using the coordinates of this point, explain how the three transformations map vertex A onto vertex A^ prime .

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

if you was gonna solve for a, a is a   < -12

yes the data was not prsented
