In triangle ABC, `bar(AD)` is median. If A = (1, 1) and D = (1, -5), then the centroid of the triangle is

In triangle ABC, AD is a median. Prove that AB + AC gt 2AD

In triangle ABC, AD is a median. Prove that AB + AC gt 2AD

In triangle ABC, angle B is right angled, AC=2 and A(2,2), B(1,3) then the length of the median AD is

In triangle ABC, angle B is right angled,AC=2 and A(2,2),B(1,3) then the length of the median AD is

In triangle ABC, angle B is right angled, AC=2 and A(2,2), B(1,3) then the length of the median AD is

In triangle ABC, medians AD and CE are drawn AD = 5, angle DAC = pi//8, and angle ACE = pi//4 , then the area of the triangle ABC is equal to

ABC is a triangle and AD is the median. If the coordinates of A are (4,7,-8) and the coordinates of centroid of triangle ABC are (1,1,1) what are the coordinates of D? (A) ((-1)/2,2,11) (B) ((-1)/2,-2,11/2) (C) (-1,2,11) (D) (-5,-11,19)

ABC is a triangle and AD is the median. If the coordinates of A are (4,7,-8) and the coordinates of centroid of triangle ABC are (1,1,1) what are the coordinates of D? (A) ((-1)/2,2,11) (B) ((-1)/2,-2,11/2) (C) (-1,2,11) (D) (-5,-11,19)

In a Delta ABC , the median AD is perpendicular to AC. If b = 5 and c = 11, then a =
