Question

How you define a quadrilateral ?

Answer 1

A quadrilateral is a polygon with four sides and four angles. Some important properties of quadrilaterals include the sum of the interior angles being 360 degrees, different classifications based on properties, such as parallelograms, rectangles, squares, rhombuses, trapezoids, and kites, and opposite sides being parallel in some quadrilaterals.

Step-by-step explanation:

A quadrilateral is a polygon with four sides and four angles.

Some important properties of quadrilaterals include:

1. The sum of the interior angles of a quadrilateral is 360 degrees.
2. Quadrilaterals can be classified into different types based on their properties, such as parallelograms, rectangles, squares, rhombuses, trapezoids, and kites.
3. Each side of a quadrilateral is adjacent to two other sides.
4. Opposite sides of a quadrilateral are parallel in parallelograms, rectangles, and squares.
5. Diagonals of some quadrilaterals, like rectangles and squares, are congruent.

For example, a square is a type of quadrilateral with four equal sides and four right angles. A rhombus is a type of quadrilateral with four equal sides, but the angles are not necessarily right angles.
