As the name itself imply the indigenous is a combination of 2 Latin indigenous ‘Quadri‘ method a different of four, and ‘latus‘ means side.

You are watching: A quadrilateral with four congruent sides One the the instances of a concave square is a Dart. That is a quadrilateral with bilateral symmetry favor a kite, however with a reflex interior angle. Quadrilaterals which have all four interior angle less than 180° are called concave quadrilaterals. There space various types of Convex Quadrilaterals:TrapeziumKiteParallelogramRectangleRhombusSquare

### Trapezium

A trapezium is a quadrilateral which has one pair that opposite sides parallel. In a consistent trapezium, non-parallel sides room equal and also its base angles space equal. ### Kite

Kite has two bag of equal nearby sides and also one pair the opposite angle equal. Diagonals the kite intersect perpendicularly. The longest diagonal line of the dragon bisects the smaller one. ### Parallelogram

A quadrilateral whose the contrary sides space equal and also parallel is called a Parallelogram. Opposite angle of a Parallelogram room equal and also its diagonals bisect each other.
