Ex.10.3 Q1 Circles Solution - NCERT Maths Class 9
Draw different pairs of circles. How many points does each pair have in common? What is the maximum number of common points?
What is known?
Pair of circles.
What is unknown?
No. of points does each pair have in common and what can be maximum common points
We can draw no. of possible pairs and can observe common points in each case
In this there are no common points.
In this there is only one common point.
In this there are two common points.
In a situation where two congruent circles are superimposed on each other, it can be understood to as if we are drawing the same circle two times.
It is therefore concluded, there can be a maximum of two points for different pairs of circles.
