Question

If ABC and DEF are two triangles such that AC = 2.5 cm, BC = 5 cm, ∠C = 75°, DE = 2.5 cm, DF = 5cm and ∠D = 75°. Are two triangles congruent?

Answer in Brief

Solution

It is given that

AC = 2.5

BC = 5

∠C = 75° 

DE = 2.5

DF = 5

∠D = 75°

Since, two sides and angle between them are equal, therefore triangle ABC and DEF are congruent.
