Given: angle b= angle bea
angle dec =~ angle c
prove: ab || cd

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
