Types of Numbers
There are different types and varieties of quadrilaterals having different properties such as different angles and sides. You can learn them here in a very easy and informative way.
After reading this tutorial you can answer these questions like
-Four vertices (corners).
-Interior angles sum to 360°.
-Exterior angles sum to 360°.
Diagonals are line segments that join two opposite vertices of a quadrilateral (corners).
A quadrilateral can have maximum two diagonal
Two sides are adjacent, if they share a common vertex.
Two angles are adjacent, if they share a common side.
Some types are also included in the definition of other types! For example a square, rhombus and rectangle are also parallelograms.
Properties of Rhombus :-
whose vertices all lie on a single circle. This circle is called the circumcircle or circumscribed circle, and the vertices are said to be concyclic. The center of the circle and its radius are called the circumcenter and the circumradius respectively. Other names for these quadrilaterals are concyclic quadrilateral and chordal quadrilateral, the latter since the sides of the quadrilateral are chords of the circumcircle.
