Q2 of 319 Page 23

The acute angle between the medians drawn from the acute of a right angled isosceles triangle is

Let the coordinates of the right-angled isosceles triangle be O(0, 0), A(a, 0) and B(0, a).



Here, BD and AE are the medians drawn from the acute angles B and A, respectively.


∴ Slope of BD = m1


Slope of AE = m2


Let θ be the angle between BD and AE.


tan θ


⇒ cos θ


⇒ cos θ =


⇒ θ


Hence, the acute angle between the medians is
