a reflection across the line y = x followed by a rotation 90° counterclockwise

a rotation 180° clockwise followed by a reflection across the x-axis

Answer 6

Well let's try to eliminate some things. We can automatically eliminate A because a reflection would cause the points to change position

Answer 7

ok

Answer 8

B is wrong too because the triangle wouldn't be in the position it is in

Answer 9

that eaves c and d

Answer 10

Right..

Answer 11

so...?

Answer 12

@jeffyblood Thanks :)

Answer 13

its D right? across the x axis with reflection?

Answer 14

It looks like it

Answer 15

Really not that har, but what most people seem to fail to see is when you rotate it, the positions of the corners change.

One of those answers has more work than needed, but if you think about that work, you will see it is able to be ingored.

Answer 16

D is wrong

Answer 17

C is wrong.

Answer 18

It's A! for plato users. You're welcome.
