PLEASE HELP! Since AB=1 and 1=BC, BC=AB by which property?
erastovalidia [21]

Substitution.

Here is an example.

Let x be equal to 3 and y equal to 3.

x=3, y=3

From this we can conclude that the values of both x and y are equal to three therefore x and y have the same value and are equal.

x\wedge y=3\Longrightarrow x=y

Here in your case we have:

AB=1, BC=1 \\AB\wedge BC=1\Longrightarrow AB=BC

Hope this helps.
