In ABC right angle triangle with angle ABC as 90 degree and angle BAC is 60 Deg .
In ABC right angle triangle with angle ABC as 90 degree and angle BAC is 60 Deg .So, angle ACD is 180–60 or 30 degree.
In ABC right angle triangle with angle ABC as 90 degree and angle BAC is 60 Deg .So, angle ACD is 180–60 or 30 degree.As AD is angle bisector of angle BAC = 60 degree angle BAD = angle CAD = 30 degree and ADB is 180–90–30 or 60 degree
In ABC right angle triangle with angle ABC as 90 degree and angle BAC is 60 Deg .So, angle ACD is 180–60 or 30 degree.As AD is angle bisector of angle BAC = 60 degree angle BAD = angle CAD = 30 degree and ADB is 180–90–30 or 60 degreeAs triangle ACD is isosceles triangle with two angles as 30 degree , DC = AD.
In ABC right angle triangle with angle ABC as 90 degree and angle BAC is 60 Deg .So, angle ACD is 180–60 or 30 degree.As AD is angle bisector of angle BAC = 60 degree angle BAD = angle CAD = 30 degree and ADB is 180–90–30 or 60 degreeAs triangle ACD is isosceles triangle with two angles as 30 degree , DC = AD.In triangle BAD , BD = AD Sin 30 = AD/2 and DC= AD
