Question

2.Which of the quadrilaterals having diagonals of equal length?

a) rhombus
b)parallelogram
c)kite
d)sqaure
​

Answer 1

d) square have equal diagonals,the diagonals also bisects at 90°

rectangles too have equal diagonals (extra)

Answer 2

Answer:

• Option (D) Square is the required answer

Diagonals of Square are equal in length .

Additional Information

• In Square All sides area equal in length .

• Sum of all angles in a square is 360°

• All angles are equal (i.e. 90° each)

• Perimeter of Square = 4 × Side

• Area of Square = Side × Side .
