The number of circles that touch all the three lines \(x+y-1=0, x-y-1=0\) and \(y+1=0\) is
- A \(2\)
- B \(3\)
- C \(4\)
- D \(1\)
Answer & Solution
Correct Answer
(C) \(4\)
Step-by-step Solution
Detailed explanation
Given lines are \[ x+y-1=0, x-y-1=0 \text { and } y+1=0 \] These lines form a triangle the total number of circles that touches all the three sides of a triangle are 4. \([\because\) One is incircle of a triangle and when we extend the sides of a triangle we will get the three…
