Answer 1

Answer:

It is a square

All sides r congruent

All angles r congruent

Answer 2

Answer:

If all sides and all angles of $a$ quadrilateral are congruent, it is called $a$ square.

Step-by-step explanation:

• A quadrilateral each of whose angle is of 90° and have all equal sides is called a square.
• The diagonals of the square are also equal.
• The diagonals of the square intersect each other and divides it into equal lengths.

Consider ABCD is a square.

Then,

AB = BC = CD = AD (Sides of the square)

AC = BD (Diagonals of the square)

AO = OC = OB = OD

∠$A$ = ∠B = ∠$C$ = ∠D = 90°

Therefore, a square is a quadrilateral in which all sides and all angles are congruent.
