A=(0,0)
B=(1,0)
C=(0,1)
AB=√(0-1)^2+(0-0)^2
→AB=1
→c=1
BC=√(1-0)^2+(0-1)^2
→BC=√2
→a=√2
CA=√(0-0)^2+(0-1)^2
→CA=1
→b=1
Now,
Incentre=
({ax1+bx2+cx3}/{a+b+c},{ay1+by2+cy3}/{a+b+c}
On putting required value and solving it we get
→(1/(2-√2),(1/(2-√2))
→({2-√2}/2,{2+√2}/2)
Plz follow me nd mark me as brainliest.
