Question

In Fig 7.13, AD = CD and AB = CB. State the three pairs of equal parts in ΔABD and ΔCBD.

Answer 1

Answer:

BD=BD

angle A= angle C

angle ABD= angle CBD

Step-by-step explanation:

As given in fig.

AD=CD

AB=CB

and BD =BD ( common side)

hence ΔABD≅ ΔCBD.

so,

BD=BD

∠A= ∠C

∠ABD=  ∠CBD

Answer 2

Answer:

BD=BD

angle A= angle C

angle ABD= angle CBD

Step-by-step explanation:

As given in fig.

AD=CD

AB=CB

and BD =BD ( common side)

hence ΔABD≅ ΔCBD.

so,

BD=BD

∠A= ∠C

∠ABD=  ∠CBD
