Rectangle
A rectangle is a four-sided polygon with opposite sides that are equal in length and four right angles
A rectangle is a four-sided polygon with opposite sides that are equal in length and four right angles. It is a special type of parallelogram where all angles are right angles. The sides that are opposite and parallel to each other are called the length, while the other two sides are called the width.
Properties of a rectangle:
1. All angles are right angles: Each angle in a rectangle measures 90 degrees.
2. Opposite sides are equal: The length of one pair of opposite sides is equal to the length of the other pair.
3. Diagonals are congruent: The diagonals of a rectangle are equal in length and bisect each other.
4. Perimeter: The perimeter of a rectangle is the sum of all its sides, given by the formula P = 2(length + width).
5. Area: The area of a rectangle is the product of its length and width, given by the formula A = length × width.
Example:
Suppose we have a rectangle with a length of 6 units and a width of 4 units. We can calculate its perimeter and area as follows:
Perimeter = 2(6 + 4) = 2(10) = 20 units
Area = 6 × 4 = 24 square units
Rectangles are commonly found in everyday objects, such as doors, windows, picture frames, and computer screens. They have numerous applications in mathematics, engineering, architecture, and various other fields.
