You can put this solution on YOUR website! You have probably drawn a picture with all appropriate labels to help you. I will assume that first.
STATEMENT 1: angle DBC and angle ABC are right angles
REASON 1: Given
STATEMENT 2: DC = AC
REASON 2: Given
STATEMENT 3: BC = BC
REASON 3: reflexive property of equality.
STATEMENT 4: angle DCB ~ angle ACB.
REASON 4: If a point is equidistant from two other points then it is an angle bisector.
STATEMENT 5: triangle(DBC) ~ triangle(ABC)
REASON 5: ASA
