Question

if two of the medians of a triangle are equal, show that the Triangle is isosceles. ​

Answer 1

Step-by-step explanation:

Taking A as origin, let position vectors of B and C be b and c respectively. So, the position vectors of the mid-points FF and EE of sides AB and AC are and respectively. Hence the triangle is isosceles. Hence proved
