Question

 <ABC is a right angle;line BD is an angle bisector of <ABC. I need to prove that m< DBC=45 Can you please help me using the two column prove

Answer 1

   statements                      reasons

               

1)    < ABC = 90   --------------right angle                     

2)    <ABD = <DBC --------------line BD is angle bisector

3)    <ABD +<DBC =90---------angle addition postulate

4)     2 <DBC =90-------------from   statement 2 and 3

5)   <DBC =45----------------proved
