Question

Given below are measurements of some parts of two triangles. Examine whether the two triangles are congruent or not, by the ASA congruence rule. In the case of congruence, write it in symbolic form.

∆DEF, ∠D = 60º, ∠F = 80º, DF = 6 cm.

∆PQR, ∠Q = 60º, ∠R = 80º, QP = 6 cm.

Answer 1

∠D = ∠Q

∠F = ∠R

Side DF = Side PQ

So, ∆DEF ≅ ∆PQR.......(ASA congruence criterion)
