Quadrilateral
A closed figure with four sides and four vertices, including squares, rectangles, and trapezoids.
A quadrilateral is a geometric shape that has four sides, four vertices (corners), and four angles. In simpler terms, it is a four-sided polygon. Quadrilaterals can take on different shapes and sizes, and they can be classified based on their properties and characteristics.
Some common types of quadrilaterals include:
1) Square: A quadrilateral in which all four sides are of equal length, and all four angles are right angles (90 degrees).
2) Rectangle: A quadrilateral in which all four angles are right angles (90 degrees), but opposite sides are of equal length.
3) Rhombus: A quadrilateral in which all four sides are of equal length, but opposite angles are equal.
4) Parallelogram: A quadrilateral in which opposite sides are parallel, and equal in length.
5) Trapezium: A quadrilateral in which one pair of opposite sides are parallel, but the other pair are not.
Understanding the properties and characteristics of each type of quadrilateral is important for solving mathematical problems and for identifying shapes in real-world scenarios.
