Answer 7

Okay so the question first asks whether it's an enlargement or a reduction. Do you know the difference?

Answer 8

Um the enlargement is bigger and reduction gets smaller?

Answer 9

Right. So which is this?

Answer 10

reduction.

Answer 11

Clearly. It's gotten smaller. Now the question is how MUCH smaller? Look at two corresponding sides and see how long the first is compared to the second.

Answer 12

thats the part that confuses me

Answer 13

Wait is it reduction 2?

Answer 14

Answer 15

Why do you say reduction by 2?

Answer 16

The sides if you count them it changes by 2 or so i thought

Answer 17

What do you get when you count them?

Answer 18

Answer 20

And in the bottom triangle the sides are...

Answer 21
