Answer 2

Answer:

Given : All sides of square are equal.

Step-by-step explanation:

To prove : Diagonals of square are congruent.

Let ABCD be a square. Let the diagonals AC and BD intersect each other at a point O. To prove that the diagonals of a square are equal and bisect each other at right angles, we have to prove AC = BD, OA = OC, OB = OD, and AOB = 90º.

In ABC and DCB,

AB = DC (Sides of a square are equal to each other)

ABC = DCB (All interior angles are of 90)

BC = CB (Common side)

ABC = DCB (By SAS congruency)

AC = DB (Being side of congruent triangle )

hence, Diagonals of square are congruent.
