do the polygons create congruent figures?
1. d(-6,-2), e(-8,6), f(6,-2) and x(-3,-1), y(-4,3), z(3,-1)

2. g(-5,-3), h(-7,4), j(-3,-2) and k(-3,-6), l(-5,1), m(-1,-5)

They are not congruent.

Step-by-step explanation:

You need to find the distance between these points to find congruence. If just one of these doesn't match with its corresponding side, its not congruent.

DE: square root of 68

_

GH: square root of 53

DE and GH are corresponding, but they are not congruent so these polygons are not congruent.

angle addition postulate

2x=56

step-by-step explanation:

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
