Question

∆PQR was reflected and then dilated by a scale factor of 4 to create ∆P''Q''R''. Which statement explains why ∆PQR is similar to ∆P''Q''R''?

Reflections and dilations preserve side length; therefore, the corresponding sides of ∆PQR and ∆P''Q''R'' are congruent.
Reflections and dilations preserve angle measure; therefore, the corresponding angles of ∆PQR and ∆P''Q''R'' are congruent.
Reflections and dilations preserve orientation; therefore, the corresponding angles of ∆PQR and ∆P''Q''R'' are proportional.
Reflections and dilations preserve collinearity; therefore, the corresponding angles of ∆PQR and ∆P''Q''R'' are congruent.

Answer 1

am i right with D?

Answer 3

use what @dude said before

Answer 4

collinearity

do you understand what mean this word ?

Answer 5

two sides when are colinear ? what mean this ?

Answer 6

the easy way why you take it so mixed ?

Answer 7

yes D is right

Answer 8

ohh wait its B

Answer 9

why not is right D ?

Answer 10
