The side BC of DeltaABC is product to N. bisector of angle meets BC at M. Prove that angleABC+angleACN=2angleAMC

The side BC of DeltaABC is product to N. bisector of angle meets BC at M. Prove that angleABC+angleACN=2angleAMC

The side BC of a ABC is produced,such that D is one ray BC. The bisector of /_A meets BC in L as shown in Figure.Prove that /_ABC+/_ACD=2/_ALC

The sides BC of ABC is product to a point D The bisector of /_A meets side BC in L. If /_ABC=30^(@) and /_ACD=115^(@), find /_ALC

ABC is a right angled with AB=AC. Bisector of angleA meets BC at D. prove that BC=2AD

In ABC,/_A=50^(@) and BC is produced to a point D.The bisectors of /_ABC and /_ACD meet at E .find /_E .

ABC is a right triangle with AB = AC.If bisector of angle A meet BC at D then prove that BC =2 AD .

ABC is a right triangle with AB = AC .If bisector of angle A meet BC at D then prove that BC = 2 AD .

The side BC of Delta ABC is produced to D. The bisectors of angle ABC and angle ABD meet at E. If AB = AC and angle BEC = 24 ^(@). then the measure of angle ABC is :

In Figure,side BC of ABC is produced to point D such that bisetors of /_ABC and /_ACD meet at a point E* If /_BAC=68^(@), find /_BEC
