What segment is congruent to AC?<br> A. BD<br> B. BE<br> C. CE<br> D. none
Phoenix [80]
You can find the segment congruent to AC by finding another segment with the same length. So first, you need to find the length of AC.

   C - A = AC
0 - (-6) = AC   Cancel out the double negative
  0 + 6 = AC
        6 = AC

Now, find another segment that also has a length of 6.

   D - B = BD
2 - (-2) = BD   Cancel out the double negative
  2 + 2 = BD
        4 = BD
        4 ≠ 6

   E - B = BE
4 - (-2) = BE   Cancel out the double negative
  4 + 2 = BE 
        6 = BE
        6 = 6

So, the segment congruent to AC is B. BE .
