Straight Lines ...

If A(2, 2), B(-4, -4), C(5, -8) are the vertices of any triangle the length of median passes through C will be

If the distance between the points (a, 2) and (3, 4) be 8 then a =

If the area of a triangle is $$68 $$ sq. units and the vertices are $$(6, 7), (-4, 1)$$ and $$(a, -9) $$ then the value of $$a$$ is 

The co-ordinates of the vertices of a rectangle are $$(0, 0), (4, 0), (4, 3)$$ and $$(0, 3)$$. The length of its diagonal is

The straight lines $$x+y-4=0, 3x+y-4 =0, x+3y-4 =0$$ forms a triangle which is

The straight lines $$x + y - 4 =0,\ 3x + y - 4 =0$$, and $$x + 3y -4 = 0$$ form a triangle which is :

If the distance between $$(8, 0)$$ and A is $$7$$, then co-ordinates of the point A can not be

A circle that has its center its center at the origin and passes through (-8,-6) will also pass through the point: 

Do the points $$(-2, 5), (3, -4)$$ and $$(7, 10)$$ represent  the vertices of a right triangle?

Find a point on x-axis which is equidistant from $$A(7, 6)\ and\ B(-3, 4)$$
