Explain the mistake in each proof in Problems 1-2. Then describe a correct way to prove that the triangles are congruent. Identify any
additional information that is needed.
1. Given: FD BC, AB DE, and AC FE
Since FD BC, ZDFE = ZACB by the Alt. Int.
Thm. Since AB || DE, ZABC = ZEDF by
the Alt. Int 2 Thm. Also, AC = FE is given.
Therefore, AABC = AEDF by AAS Congruence
Theorem.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

hm let me think hm think think hm think yes
