The incenter of the triangle with vertices `(1,sqrt(3)),(0,0),` and `(2,0)` is `(1,(sqrt(3))/2)` (b) `(2/3,1/(sqrt(3)))` `(2/3,(sqrt(3))/2)` (d) `(1,1/(sqrt(3)))`

The incetre of the triangle with vertices (1,sqrt(3)),(0,0) and (2,0) is

The incentre of triangle with vertices (1, sqrt(3)), (0,0) and (2, 0) is

The incenter of the triangle with vertices (1,sqrt(3)),(0,0), and (2,0) is (a) (1,(sqrt(3))/(2)) (b) ((2)/(3),(1)/(sqrt(3)))(c)((2)/(3),(sqrt(3))/(2)) (d) (1,(1)/(sqrt(3)))

The incentre of a triangle with vertices (7,1),(-1,5) and (3+2sqrt(3),3+4sqrt(3)) is

(-sqrt(3)/2 + sqrt(3))/(1/sqrt(2)-1)=

The perimeter of the triangle formed by the points (0,0),(1,0) and (0,1) is 1+-sqrt(2) (b) sqrt(2)+1(c)3(d)2+sqrt(2)

(1)/(2+sqrt(3))+(2)/(sqrt(5)-sqrt(3))+(1)/(2-sqrt(5))=0
