Question
The incentre of the triangle with vertices (1, √3), (0,0) and (2,0) is
Options
A.
B.
C.
D.
Solution
Let the vertices of triangle be A(1√3), B(0,0) and C (2, 0),
Here, AB = BC = CA = 2
Therefore, it is an equilateral triangle. So the incentre coincides with centroid.
∴
⇒ (1,1/√3)
Here, AB = BC = CA = 2
Therefore, it is an equilateral triangle. So the incentre coincides with centroid.
∴
⇒ (1,1/√3)
