Question 144 (i)

ABC is an isosceles triangle with AB = AC and D is the mid-point of base BC (see the figure)
State three pairs of equal parts in the $\Delta ABD$ and $\Delta ACD$

Answer 1

Given, AB = AC
and BD = CD [ Since D is the midpoint of side BC ]
In $\Delta ABD$ and $\Delta ACD$,
AB = AC [given]
BD = CD [given]
AD = AD [common side]
