00:17

the abstract left scratching our noodles here which was kind

00:21

of a weird feeling So we drew some quick examples

00:24

you know check him out Well we started with a

square with coordinates for four corresponds to the corner of

00:41

the red square recording It's negative for negative for well

00:45

the two squares are mirror images of each other relative

00:49

to the line we drew in blue which is the

line Why equals negative acts right That that line right

00:54

there y equals negative act well reflecting the black square

00:57

across the y equals negative X line produces the red

01:01

square in the same position So this reflection is equivalent

01:04
