Question

Which property is illustrated by the following statement?
AB equals CD, so AB plus DE equals CD plus DE
A. Symmetric
B. Transitive
C. Addition
D. Distributive

Answer 1

This is the addition or additive property of equality (since you're adding DE to both sides)

Answer 2

can u help with 4 more problems

Answer 3

Postulates can be used to prove theorems.
True
False

Answer 4

which one do you think it is

Answer 5

in thinkin its true

Answer 6

wait no false

Answer 7

you are correct, postulates are axioms which are assumed to be true and they are helpful in proving theorems

Answer 8

defenitions need to be proven right

Answer 9

no, definitions are defined to be true

Answer 10

ooh

Answer 11

Use the given property to complete the statement.
Substitution: A plus B equals 180 degrees. B equals C, so A plus blank equals 180 degrees
A. angle ey
B. angle bee
C. angle see
D. None of these

Answer 12

it's what we set up (eg: let t = time)

Answer 13

B = C

Reflexive Property

The Reflexive Property states that for every real number x, x = x.



Symmetric Property

The Symmetric Property states that for all real numbers x and y,

if x = y, then y = x.



Transitive Property

The Transitive Property states that for all real numbers x, y, and z,

if x = y and y = z, then x = z.
