Question

Complete the pairs of corresponding parts if ABD congruent to EFC.

Answer 1

Answer:

The correct option is 3.

Step-by-step explanation:

Given information: ΔABD≅ΔEFC.

The corresponding sides and corresponding angles of congruent triangles are same.

In triangle ΔABD and ΔEFC,

$\angle A=\angle E$

$\angle B=\angle F$

It can be written as

$\angle B=\angle EFC=\angle CFE$

$\angle D=\angle C$

Angle B is equal to angle EFC, therefore the correct option is 3.

Answer 2

Remember the notation..

When you have a triangle called ABD, the angles may be called in theses equivalent ways>

angle A is equivalent to ∠ DAB
angle B is equivalent to ∠ ABD
angle D is equivalen to ∠ BDA

Then given that the two triangles are congruent, you can say an

angle B = angle F = ∠ EFC

So the answer is the last option of the list.
