Quadrilaterals

Quadrilaterals explained with definitions, types, key properties, and simple examples to build strong geometry fundamentals.

1.Introduction to Quadrilaterals

Learn what quadrilaterals are, how they are formed, and the basic features that define four-sided shapes in geometry.

2.Types of Quadrilaterals

Understand the different types of quadrilaterals such as parallelogram, rectangle, square, rhombus, trapezium, and kite.

3.Parallelogram

Explore the structure of a parallelogram and learn how its opposite sides and angles relate to each other.

Learn what makes a rectangle unique, including equal opposite sides and all angles being right angles.

Understand the square as a special quadrilateral with all sides equal and each angle measuring 90 degrees.

Discover the rhombus as a four-sided figure with all sides equal and diagonals that intersect at right angles.

Learn about trapeziums, which have at least one pair of parallel sides, and their key geometric properties.

Explore the shape of a kite, defined by two pairs of equal adjacent sides and symmetric diagonal properties.

9.Midpoint Theorem

Understand the midpoint theorem and how it helps relate line segments in triangles and quadrilaterals.

10.Area of a Quadrilateral

Learn different methods to calculate the area of quadrilaterals based on shape, diagonals, base, and height.
