`ABC` is a triangle. The radical centre of the circles with `AB, BC , CA` as the diameters is `(-6, 5)`. If `A(3, 2), B(2, 1)` then `C=`

The radical centre of the three circles described on the three sides of a triangle as diameter is ......... of the triangle

AB is a diameter of a circle with centre C = (-2, 5). If A = (3, -7). Find the coordinates of B.

If A(0, 0), B(1, 0) and C(1/2,sqrt(3)/2) then the centre of the circle for which the lines AB,BC, CA are tangents is

If G is centroid of Delta ABC and BC = 3, CA = 4, AB = 5 then find BG.

Construct a triangle ABC given that : AB = 5 cm, BC = 4 cm and CA = 6 cm

In a triangle, ABC, the equation of the perpendicular bisector of AC is 3x - 2y + 8 = 0 . If the coordinates of the points A and B are (1, -1) & (3, 1) respectively, then the equation of the line BC & the centre of the circum-circle of the triangle ABC will be

A triangle ABC has been enlarged by scale factor m = 2.5 to the triangle A' B'C' Calculate : the length of C'A' if CA = 4 cm.

A triangle ABC has been enlarged by scale factor m = 2.5 to the triangle A' B'C' Calculate : the length of AB, if A' B' = 6 cm.

Construct Delta ABC with sides AB = 7 cm, BC = 5 cm, CA = 6 cm.

Using a rular and compass only : (i) Construct a triangle ABC with the following data : AB = 3.5 cm, BC = 6 cm and angleABC=120^(@) . (ii) In the same diagram, draw a circle with BC as diameter. Find a point P on the circunference of the circle which is equidistant from AB and BC. (iii) Measure angleBCP .
