AP EAMCET · Maths · Properties of Triangles
In \(\triangle A B C\), with usual notation, observe the two statements given below :
(I) \(r r_1 r_2 r_3=\Delta^2\)
(II) \(r_1 r_2+r_2 r_3+r_3 r_1=s^2\)
Which of the following is correct?
- A Both I and II are true
- B I is true, II is false
- C I is false, II is true
- D Both I and II are false
Answer & Solution
Correct Answer
(A) Both I and II are true
Step-by-step Solution
Detailed explanation
We know that \(\Delta^2=r r_1 r_2 r_3\) and \(s^2=r_1 r_2+r_2 r_3+r_3 r_1\) So, both the statements are true.
