Answer:
Step-by-step explanation:
Any one side of a triangle may be considered as its base. There are different ways of calculating base of a triangle.
(1) Base = (2*area)/ corresponding altitude
(2) If ABC is an acute triangle & BC is considered as its Base
Then, BC = √(AB² - AC² + 2BC*CX) , where CX is projection of AC on BC.
(3) If, ABC is an obtuse triangle with angle C as obtuse & BC is considered as its base.
Then BC = √( AB² - AC² - 2BC*CX), where CX is projection of AC on BC extended.
(4) If triangle is a right triangle right angled at C. Then BC = √( AB² - AC²)
(5) Or apply law of Cosine or sine…. using angles …
