Question

State whether the following triangles are congruent are not? Give reasons for your answer

Answer 1

ΔLMN ≅ Δ RTS  , Congurent Triangles & ΔABC ≅ Δ DEF Congruent Triangles

Step-by-step explanation:

ΔLMN ≅ Δ RTS

as MN = ST  = 3 cm

     LN  = RS = 4 cm

   ∠LMN = ∠RTS = 80°

Using SAS

ΔLMN ≅ Δ RTS

Congurent Triangles

in ΔABC

∠A = 180° - ∠B - ∠C = 180° - 50° - 70° = 60°

in Δ DEF

∠E = 180° - ∠D - ∠F = 180° - 60° - 70° = 50°

ΔABC ≅ Δ DEF

BC = FE  ( given)

∠A = ∠D = 60°

∠B = ∠E = 50°

∠C = ∠F = 70°

ΔABC ≅ Δ DEF
