Answer: AC ≅ EG
Explanation:
Given : quadrilateral ABCD≅quadrilateral EFGH
We know that if two quadrilaterals are congruent then the corresponding parts are congruent.
i.e. Corresponding sides and diagonals of congruent quadrilaterals are congruent.
i.e. If quadrilateral ABCD≅quadrilateral EFGH, then
AB ≅ EF [ First two vertices ]
BC ≅ FG [Middle two vertices]
CD ≅ GH [Last two vertices]
DA ≅ GH [Last and First vertices]
AC ≅ EG [First and Third vertices]
BD ≅ FH [Second and Fourth vertices]
Therefore, the correct answer is : AC ≅ EG
