the middle one

#

Congruent to what?

crimson vine Jan 10, 2023, 8:27 PM

#

to each other

#

elfin spade Jan 10, 2023, 8:28 PM

#

Oh. Well, that's the whole point.

#

They need to be equal.

crimson vine Jan 10, 2023, 8:28 PM

#

the sides are congruent

#

elfin spade They need to be equal.

#

if one side is 3x+5 the other one must be the same value right

#

crimson vine if one side is 3x+5 the other one must be the same value right

Yes. So, 3x + 5 = x + 6.

crimson vine Jan 10, 2023, 8:29 PM

#

OH

#

this can be another scenario

elfin spade Jan 10, 2023, 8:29 PM

#

There are three options that you can put these angles into.

Both at the base.
3x + 5 at the base, x + 6 opposite of the base.
x + 6 at the base, 3x + 5 opposite of the base.

@elfin spade can u explain please

Well, as angles A and C are the same, then sides AB and BC are the same.
So, we either need AB = AC or BC = AC. So, both statements are needed (since just one of them can't be true without the other).

crimson vine Jan 10, 2023, 8:44 PM

#

it said AB equal to AC is the correct answer

#

not both

#

OH
