wht u supposed to do

@freckles

OpenStudy (tkhunny):

Start talking about corresponding parts. Steps 1) and 2) might be the same, but referring to different pairs of angles.

OpenStudy (anonymous):

@tkhunny

OpenStudy (tkhunny):

Step #2 is no good. You have referred to the entire angle, rather than the two halves. Consider \(\angle DBA\;and\;\angle DBC\), then do the same thing at the bottom.

OpenStudy (anonymous):

to what bottom?

OpenStudy (anonymous):

is the reason for number 3 correct?

OpenStudy (tkhunny):

ABC is the top ADC is the bottom Get them both in that #2.

OpenStudy (tkhunny):

No good on #3. Those are not adjacent angles. Given the two sets of angles in #2, they just might be the pair of angles we are looking for since we know the sum of the interior angles of a triangle.

OpenStudy (anonymous):

You just gave me angle DBA and angle DBC for #2

OpenStudy (tkhunny):

... AND BDA and BDC. Two corresponding pairs with the same angle bisector. The mentioned both sets in the Given. You mention both sets in #2.

OpenStudy (tkhunny):

|dw:1449869236943:dw| State that. Then, state the same thing for the bottom angle - the one centered and bisected at D. Put BOTH statements on #2, just like the "Given" has both angles bisected on #2.
