Question

obObserve the figure and state the three pairs of equal parts in triangles ABC and

DCB.​

Answer 1

Answer:

Step-by-step explanation:

∠ABC = 40 + 30 = 70°

∠DCB = 40 + 30 = 70°

Therefore,

In ΔABC and ΔDCB

∠C      =    ∠B

∠ABC = ∠DCB

Since two angles are equal, third one will also be equal,

Therefore,

ΔABC ≅ ΔDCB ( AAA )
