In ∆ABD and ∆ACD, AB=AC (given), AD=AD (common), angle ADB = angle ADC (since AD is an altitude), Therefore by SAS congruence rule ∆ADB congruence to ∆ACD. AB=AC (by CPCT), angle BAD = angle CAD (by CPCT)

The Pythagorean theorem, also known as Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

let ABC is a triangle and AD is any median on BC. now we have two triangles ABD and ACD. In ∆ABD, AB > AD......eq^n(1), In ∆ACD, AC > AD.......eq^n(2), adding (1) & (2), we get AB + AC > AD + AD, AB + AC > 2AD
