Various Types of Quadrilaterals
In this section, we shall study about various types of quadrilaterals.
A quadrilateral having exactly one pair of parallel sides, is called a trapezium.
A quadrilateral is a parallelogram if it’s both pairs of opposite sides are parallel and equal.
A parallelogram having all sides equal is called a rhombus.
A parallelogram who’s each angle is a right angle, is called a rectangle.
A square is a rectangle with a pair of equal adjacent sides.
In other words, a parallelogram having all sides equal and each angle equal to a right angle, is called a square.
Class 6 Maths Exercise 5.7 Important Questions for Practice
Name each of the following parallelograms: (i) All sides are equal. (ii) Each angle is right angle. (iii) One pair of sides is parallel and non-parallel sides are equal.
(i) A parallelogram in which all sides are equal called Rhombus.
(ii) A parallelogram who’s each angle is a right angle is called a rectangle.
(iii) A parallelogram whose One pair of sides is parallel and non-parallel sides are equal is called trapezium
What do all Quadrilaterals have in common?
There are many different kinds of quadrilaterals, but all have several things in common:
All of them have four sides, are coplanar, have two diagonals, and the sum of their four interior angles equals 360 degrees.
A quadrilateral is a kite if it has two pairs of equal adjacent sides and unequal opposite sides.
Class 6 Maths Exercise 5.7 Extra Questions with Answer
What are special Quadrilaterals?
Many special quadrilaterals have special attributes. A trapezoid has exactly one pair of parallel sides. A parallelogram has two pairs of equal parallel sides. A rectangle is a parallelogram with 4 right angles. A rhombus is a parallelogram with 4 equal sides.
How many elements are required to construct a unique quadrilateral?
Thus a quadrilateral has 10 elements (4 sides, 4 angles and 2 diagonals) or measurements. To construct a unique quadrilateral, we need to know 5 measurements (elements).
How do you classify quadrilaterals?
A quadrilateral is a polygon with four sides.
A rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals.
A rhombus is a parallelogram with four congruent sides.
A trapezoid is a quadrilateral with exactly one pair of parallel sides.
