Q. 1444.4( 16 Votes )

ABC is an isosceles triangle with AB = AC and D is the mid-point of base BC (Fig. 6.48).

A. State three pairs of equal parts in the triangles ABD and ACD.

B. Is ∆ABD ∆ACD. If so why?


Answer :

Given: AB = AC; D is midpoint of BC


As D is midpoint of BC


BD = DC


In Δ ADB and Δ ADC


AB = AC (given)


BD = DC (D is midpoint of BC)


AD = AD (common)


these are all 3 equal parts of triangles ABD and ACD


yes ∆ABD ∆ACD


Because it follows SSS congruence criterion
