Properties of parallelogram,Rectangle,square,rhombus,trapezium......
Answers
Answer:
parallelogram
Opposite sides are congruent (AB = DC).
Opposite angels are congruent (D = B).
Consecutive angles are supplementary (A + D = 180°).
If one angle is right, then all angles are right.
The diagonals of a parallelogram bisect each other.
Each diagonal of a parallelogram separates it into two congruent triangles.
Rectangle
A rectangle is a quadrilateral.
The opposite sides are parallel and equal to each other.
Each interior angle is equal to 90 degrees.
The sum of all the interior angles is equal to 360 degrees.
The diagonals bisect each other.
Both the diagonals have the same length.
Square
All sides and angles are congruent.
Opposite sides are parallel to each other.
The diagonals are congruent.
The diagonals are perpendicular to and bisect each other.
A square is a special type of parallelogram whose all angles and sides are equal.
Rhombus
All sides of the rhombus are equal.
The opposite sides of a rhombus are parallel.
Opposite angles of a rhombus are equal.
In a rhombus, diagonals bisect each other at right angles.
Diagonals bisect the angles of a rhombus.
The sum of two adjacent angles is equal to 180 degrees.
Trapezium
Like other quadrilaterals, the sum of all the four angles of the trapezium is equal to 360° A trapezium has two parallel sides and two non-parallel sides. The diagonals of regular trapezium bisect each other.
