Properties of the Rectangle, Rhombus, and Square
When dealing with quadrilaterals, it’s essential to understand the properties of specific types, such as rectangles, rhombuses, and squares. These properties can help you identify and work with these shapes in various mathematical and real-world contexts.
Rectangle Properties
A rectangle is a quadrilateral with four right angles (90-degree angles). The properties of a rectangle include:
- Opposite sides are equal: The lengths of the opposite sides of a rectangle are equal.
- Opposite angles are equal: The measures of the opposite angles of a rectangle are equal.
- All internal angles are right angles: Each internal angle of a rectangle measures 90 degrees.
- Diagonals bisect each other: The diagonals of a rectangle intersect at their midpoints.
- Diagonals are equal: The lengths of the diagonals of a rectangle are equal.
📝 Note: A rectangle is a special type of parallelogram where all internal angles are right angles.
Rhombus Properties
A rhombus is a quadrilateral with all sides of equal length. The properties of a rhombus include:
- All sides are equal: The lengths of all four sides of a rhombus are equal.
- Opposite angles are equal: The measures of the opposite angles of a rhombus are equal.
- Diagonals bisect each other: The diagonals of a rhombus intersect at their midpoints.
- Diagonals are perpendicular: The diagonals of a rhombus intersect at right angles (90 degrees).
- Diagonals form four congruent right triangles: The diagonals of a rhombus divide the shape into four congruent right triangles.
📝 Note: A rhombus is a special type of parallelogram where all sides are of equal length.
Square Properties
A square is a quadrilateral with all sides of equal length and all internal angles are right angles. The properties of a square include:
- All sides are equal: The lengths of all four sides of a square are equal.
- All internal angles are right angles: Each internal angle of a square measures 90 degrees.
- Diagonals bisect each other: The diagonals of a square intersect at their midpoints.
- Diagonals are perpendicular: The diagonals of a square intersect at right angles (90 degrees).
- Diagonals are equal: The lengths of the diagonals of a square are equal.
- Diagonals form four congruent right triangles: The diagonals of a square divide the shape into four congruent right triangles.
📝 Note: A square is a special type of rectangle and rhombus, as it satisfies the properties of both shapes.
