Question

∆ABC is mapped to ∆A'B'C' using each of the given rules in the table below. Place a checkmark in the correct column for each mapping to state if the resulting mapping would make ∆ABC congruent or not congruent to ∆A'B'C'.

∆ABC is congruent to ∆A^' B^' C'
∆ABC is NOT congruent to ∆A^' B^' C'

(x,y) → (x+5,y)

(x,y) → (5x,5y)

(x,y) → (.5x,.5y)

(x,y) → (x,-y)

(x,y) → (-x,-y)

Answer 1

For reference you can look at the attachment

• I have taken three points (1,1),(2,1),(3,3)

Then converted them accordingly

#1(Graph 2)

• Yes

#2(Blue dots on graph 1)

• No

They are similar but not equal

#3(Purple dots)

• No

Similar but not equal

#4(Green dots)

• Yes

#5(Black dots)
