Answer:
Explanation:
Given are some properties of triangles and we have to check whether they are correct
i) Only two of three angle bisectors of the internal angles of a triangle are concurrent.
This is incorrect since all three angle bisectors concur at incentre
ii) The circumcenter of a triangle is the point where the perpendicular bisectors of the sides meet.
-- correct because the meeting point is equidistant from all three vertices
iii) Given any three non-collinear points, there exists exactly one circle that passes through the points.
-- correct because any three points determine a circle
iv) Given any three non-collinear points, there exists exactly one circle that passes through the points.
-- Correct
v) The incenter of a triangle is the point where the angle bisectors meet.
-- Correct and the centre is equidistant from the sides of the triangle
