Question

In ∆ ABC, it is known that ∠B = ∠C. Imagine you have another copy of ∆ ABC
(i) Is ∆ ABC ≅ ∆ ACB?
(ii) State the three pairs of matching parts you have used to answer (i).
(iii) Is it true to say that AB = AC?

Answer 1

(i) Yes $△ABC\cong △ACB$.
(ii) We have used $\angle ABC=\angle ACBand\angle ACB=\angle ABCagain$.
Also BC = CB


(iii) Yes, it is true to say that AB = AC since $\angle ABC=\angle ACB$.
