The congruent sides needs to be written in the proper order.

(5x + 15) = 105 -15 -15 5x = 90 5 5 x = 18

Page 4: N ≅   R

These are congruentby SSS

x - 6 = 4 +6 +6 x = 10

These are congruentby ASA

2x + 6 = 32 -6 -6 2x = 26 2 x = 13

These are congruentby ASA

2x - 24 = x -x -x x - 24 = 0 +24 +24 x = 24

Equality and congruence mean that something is the same.

Equality is used with numbers.

Congruency means that something is the same size.

90 + 90 + x + x + 105 = 540 285 + 2x = 540 -285 -285 2x = 255 2 2 x = 127.5

109 + 72 + 76 + x = 360 257 + x = 360 -257 -257 x = 103

90 + 90 + 101 + 101 + x = 540 382 + x = 540 -382 -382 x = 158
