In a triangle ABC, let ∠ C = π /2, if r is the inradius and R is the circumradius of the triangle ABC, then 2(r+R) equals :
Text Solution
Verified by ExpertsThe correct answer is:
C
∠ C = π /2
r = (s – c) tan 
∴ C = 90 °
r = s – 2R
2r + 2R = 2 (s – 2R) + 2R.
= 2s – 2R
= (a + b + c) – 
C = 90 °
= a + b + c – c
= a + b
