Question

Which shape in the following is a square?

• A. \rule{1cm}{1cm} (Square shape box)
• B. \textbf{O} (Circle)
• C. \rule{1cm}{0.5cm} (Rectangle-like bar)
• D. \(\triangle\) (Triangle)

Hint:

A square is the only shape with four equal sides and all angles equal to 90\degree.

Answer 1

The Correct Option is A

Step 1: Know the properties of a square
A square has:
- Four equal sides
- Four right angles (each 90\degree)
- All sides are equal and opposite sides are parallel

Step 2: Check each option
(A) Clearly a square — all sides equal, right angles $\Rightarrow$ Correct
(B) Circle — no sides or angles $\Rightarrow$ Not a square
(C) Rectangle/bar — opposite sides equal, but not all $\Rightarrow$ Not a square
(D) Triangle — has only 3 sides $\Rightarrow$ Not a square
\[ \boxed{\text{Correct Answer: (A) Square shape box}} \]
