A triangle has side lengths 18, 24 and 30. Find the area of the triangle whose vertices are the incentre, circumcentre and centroid of the triangle.

Statement-1: For triangle whose two vertices are ends of a double ordinate for a parabola and third vertex lies on axis of same parabola incentre,circumcentre,centroid are collinear.statementr-2: In isosceles triangle incentre,circumcentre,orthocentre,centroid all lie on same line.

The centroid of a triangle is (2,4) and circumcentre is (1,7), then find the orthocentre .

Statement 1: If in a triangle, orthocentre, circumcentre and centroid are rational points, then its vertices must also be rational points. Statement : 2 If the vertices of a triangle are rational points, then the centroid, circumcentre and orthocentre are also rational points.

If the circumcentre of a triangle lies at the point (a, a) and the centroid is the mid - point of the line joining the points (2a+3, a+4) and (a-4, 2a-3) , then the orthocentre of the triangle lies on the line

In a triangle, if orthocentre, circumcentre, incentre and centroid coincide, then the triangle must be
