Defining a rectangle
Step 1: A rectangle is a four
-sided shape with opposite sides that are equal in length and all angles that are right angles (90°).
Evaluating shapes
Step 2: Analyze the options:
- (A) \(\Box\): Represents a square, which is a special type of rectangle with all sides equal.
- (B) \(\blacksquare\): Also represents a square, not a general rectangle.
- (C) \(\rectangle\): Represents a general rectangle, with opposite sides equal but not necessarily all sides equal.
- (D) \(\triangle\): Represents a triangle, which has three sides.
Clarifying the answer
Step 3: While a square is a type of rectangle, the symbol \(\rectangle\) specifically denotes a rectangle (often implying a non
-square rectangle in technical contexts).
Thus, the correct answer is (C).
