Question
State, whether the pairs of triangles given in the following figures are congruent or not:
Δ ABC in which AB = 2 cm, BC = 3.5 cm and ∠C = 80° and Δ DEF in which DE = 2 cm, DF = 3.5 cm and ∠D = 80°.
Solution
In Δ ABC, AB = 2 cm, BC = 3.5 cm and ∠C = 80° and in ∆ DEF, DE = 2 cm, DF = 3.5 cm and ∠D = 80°
From the figure, we see that two corresponding sides are equal but their included angles are not equal.
Hence, these are not congruent triangles
