• A. Square and Rectangle
• B. Square and Rhombus
• C. Only Square
• D. Equilateral triangle

Answer 1

Answer: (A), (B)

Square and Rhombus

Square and Rhombus have all of its sides equal.

Square:

$\Rightarrow AB=BC=CD=DA$

Rhombus:

$\Rightarrow PQ=QR=RS=SP$


Square and Rectangle have all of its angles equal to ${90}^{\circ }$.

Square:

$m\angle A=m\angle B=m\angle C=m\angle D={90}^{\circ }$

Also, square is a special type of quadrilateral with equal sides and equal angles.

Rectangle:
$m\angle P=m\angle Q=m\angle R=m\angle S={90}^{\circ }$
