Which of the following pairs of triangle are congruent by ASA condition?
In fig. 37, AD bisects A and AD and AD ⊥ BC.
(i) Is ΔADB ≅ ΔADC?
(ii) State the three pairs of matching parts you have used in (i)
(iii) Is it true to say that BD = DC?
Draw any triangle ABC. Use ASA condition to construct other triangle congruent to it.
In Δ ABC, it is known that ∠B = C. Imagine you have another copy of Δ ABC
(i) Is ΔABC ≅ ΔACB
(ii) State the three pairs of matching parts you have used to answer (i).
(iii) Is it true to say that AB = AC?
In Fig. 38, AX bisects ∠BAC as well as ∠BDC. State the three facts needed to ensure
that ΔACD ≅ ΔABD
In Fig. 39, AO = OB and ∠A = ∠B.
(i) Is ΔAOC ≅ ΔBOD
(ii) State the matching pair you have used, which is not given in the question.
(iii) Is it true to say that ∠ACO = ∠BDO?
