Karnataka State Syllabus Class 6 Maths Chapter 5 Understanding Elementary Shapes Ex 5.7
Question 1.
Say True or False:
a) Each angle of a rectangle is a right angle. – True
b) The opposite sides of a rectangle are equal in length. – True
c) The diagonals of a square are perpendicular to one another. – True
d) All the sides of a rhombus are of equal length. – True
e) All the sides of a parallelogram are of equal length. – False
f) The opposite sides of a trapezium are parallel. – False
Question 2.
Give reasons for the following:
Solution:
a) A square can be through of as a special rectangle.
In a rectangle all the interior angles are of the same measure i,e, 90° and the opposite side of the rectangle are of the same length where as in case of a square, all the interior angles are of 90° and all the sides are of the same length in other words, a rectangle with all sides equal becomes a square there, a square is a special rectangle.
b) A rectangle can be through of as a special parallelogram.
Opposite sides of a parallelogram are parallel and equal in a rectangle, the opposite sides are parallel and equal also, all the interior angles of the rectangle are of the same Measure, i,e. 90°. in other words, a parallelogram with each angle a right angle becomes a rectangle Therefore a rectangle can be thought of as a specific parallelogram.
c) A square can be through of as a special parallelogram.
All sides of a rhombus and a square are equal However, in case of a square, all interior angles are of 90° Measure. A rhombus with each angle a right angle becomes a square Therefore a square can be thought of as a special rhombus.
d) Squares, rectangles, parallelograms are all quadrilaterals.
All are closed figure made of 4 line segments Therefore all these are quadrilaterals.
e) Square is also a parallelogram. Opposite sides of a parallelogram are parallel and equal in a square, the opposite sides are parallel and the lengths of the four sides are equal Therefore a square can be thought 6 f as a special parallelogram.
Question 3.
A figure is said to be regular if its sides are equal in length and angles are equal in measure, Can you identify the regular quadrilateral?
Solution:
In a square, all the interior angles are 90° and all the sides are of the same length Therefore a square is a regular quadrilateral.
