Question

prove that the three times the sum of square of the sides of a triangle is equal to the four times the sum of the square of the median of a triangle​

Answer 1

Answer:

Apollonius theorem states that the sum of the squares of two sides of a triangle is equal to twice the square of the median on the third side plus half the square of the third side. Hence, three times the sum of squares of the sides of a triangle is equal to four times the sum of squares of the medians of the triangle
