Study Notes
Types of Quadrilaterals
- Rectangle: A quadrilateral with all angles being right angles (90°) and opposite sides of equal length.
- Square: A rectangle with all sides of equal length.
- Rhombus: A quadrilateral with all sides of equal length, but not necessarily with right angles.
- Trapezoid (or Trapezium): A quadrilateral with at least two pairs of opposite sides that are not parallel.
- Kite: A quadrilateral with two pairs of adjacent sides of equal length, and the angles between them being equal.
- Parallelogram: A quadrilateral with opposite sides being parallel.
- Irregular Quadrilateral: A quadrilateral that does not fit into any of the above categories.
Properties of Quadrilaterals
General Properties
- A quadrilateral has 4 sides, 4 vertices, and 4 angles.
- The sum of the interior angles of a quadrilateral is 360°.
Properties of Specific Types of Quadrilaterals
-
Rectangle and Square:
- Opposite sides are equal and parallel.
- Diagonals are equal and bisect each other.
-
Rhombus:
- Diagonals are perpendicular and bisect each other.
- Opposite angles are equal.
-
Parallelogram:
- Opposite sides are parallel and equal.
- Diagonals bisect each other.
-
Trapezoid (or Trapezium):
- No specific properties, but can have some of the properties of parallelograms or rectangles.
