Properties of Parallelogram
|
We know that a four sided closed figure is called a quadrilateral. There are different kinds of quadrilaterals. One of them is a Parallelogram. A parallelogram has four sides. The opposite sides are parallel and equal. The point where two adjacent sides meet is called Vertex. A parallelogram has four vertices. There is an angle at each vertex. Hence A parallelogram has four angles. The angles formed at opposite vertices are equal in measure. The line joining the opposite vertices is called a diagonal. A parallelogram has two diagonals. The diagonals of a parallelogram bisect each other.  
Rhombus: Rhombus is a special type of parallelogram. The opposite sides of a rhombus are parallel. For a rhombus all the sides are equal. In a rhombus opposite angles are equal diagonals bisecting each other at right angles? |  Rectangle: A rectangle is another type of parallelogram. In a rectangle the opposite sides are parallel and equal. In a rectangle all the angles are right angles. In a rectangle the diagonals are equal in length and bisect each other.  Square: A square is another type of parallelogram. In a square all the sides are equal and all the angles are right angles. In a square the diagonals are equal in length and bisect each other at right angles.  |
I am very impressed by your post and in my opinion a rhombus is a type of parallelogram,what distinguishes its shape is that all four of its sides are congruent.
ReplyDeleteSides-all 4 sides are congruent
Angles-diagonals bisect vertex angles
Diagonals-diagonals are perpendicular
Area-A square is a rhombus and a rectangle. In other words, if each angle of a rhombus is 90°,then it's a square.
