Answer 1

Step-by-step explanation:

The side opposite to vertex A is BC.

(b) The vertex opposite to side AB is C.

(c) The angle opposite to side AB is ∠ACB.

(d) The angle made by the sides CB and CA is ∠ACB..

Examine whether the given triangles are congruent or not.

Solution:

Here,

AB = DE = 3 cm

BC = DF = 3.5 cm

AC = EF = 4.5 cm

ΔABC = ΔEDF (By SSS rule)
