Which of the following shapes has four equal sides and four right angl...
The Answer is Square (b)Explanation:
A square is a two-dimensional shape that has four equal sides and four right angles. It is a special type of rectangle where all sides are equal.
Characteristics of a Square:
- All sides of a square are equal in length.
- The opposite sides of a square are parallel.
- All four angles of a square are right angles (90 degrees).
- The diagonals of a square are equal in length and bisect each other at right angles.
- The perimeter of a square is equal to four times the length of one side.
- The area of a square is equal to the square of one side.
Comparison with Other Shapes:
Let's compare the given options with the characteristics of a square:
- Circle: A circle does not have equal sides or right angles, so it does not meet the criteria.
- Triangle: A triangle has three sides, not four, so it does not meet the criteria.
- Rectangle: A rectangle has four right angles, but not all sides are equal in length. Therefore, it does not meet the criteria.
- Square: A square has four equal sides and four right angles, so it meets all the criteria.
Conclusion:
Among the given options, only the square (b) has four equal sides and four right angles. Therefore, the correct answer is option 'B'.
