c) transitive property of congruence
d) substitution property of congruence

Answer 1

If
A = B

Answer 2

look up the definitions for those properties

Answer 4

i dont get it

Answer 5

what school do you go to

Answer 6

Answer 7

Well i can give you a hint; its not d

Answer 8

They give you a statement in the form,

IF A = B ; THEN B = A

Answer 9

but i dont get it

Answer 10

look at the definition for symmetric property of equality here

Answer 11

ok

Answer 12

you see what it means, like a mirror at the equals sign reflecting the equation around symmetrically just flip er over

Answer 13

which does not change anything

Answer 14

ST = QR ; QR = ST

Answer 15

same

Answer 16

@DanJS

Answer 17

oh, i said symmetric property

Answer 18

If you have something like

ST = QR

if you apply the symmetric property (just flip it over the equals sign), you get

QR = ST

Which is what they want you to show.
