The construction of triangle ABC in which AB=5 cm, angle A=60 degree is possible when difference of BC and AC is given . Why?
Dear student,
Here is the link for the construction of a triangle when length of the base, one of its base angles and the difference between the other two sides are given and its justification. I hope that it is useful.
