In the adjoining figure, E is a … WebIn the adjoining figure, medians AD and BE of ∆ABC meet at the point G, and DF is drawn parallel to BE. Prove that (i) EF = FC (ii) AG : GD = 2 : 1. ... BD/AD = AD/DC = AB/AC. Because corresponding sides of similar triangles are proportional. BD/AD = AD/DC. By cross multiplication, we get, AD 2 = BD × CD. AD 2 = 2 × 8 = 16.

WebGiven: BO = OD To prove: ar(∆ABC) = ar(∆ADC) Proof: Since BO = OD, O is the mid point of BD. We know that a median of a triangle divides it into two triangles of equal areas. CO is a median of ∆BCD. i.e., ar(∆COD) = ar (∆COB) ...(i) AO is a median of ∆ABD. i.e., ar(∆AOD) = ar(∆AOB) ...(ii) From (i) and (ii), we have: WebIn the adjoining figure, AB = AC and AD is bisector of∠A.
