Lines `p ,\ q\ a n d\ r` are concurrent. Also, lines `p ,\ r\ a n d\ s` are concurrent. Draw a figure and state whether lines `p ,\ q ,\ r\ a n d\ s` are concurrent or not.

Lines p ,\ q\ a n d\ r are concurrent. Also lines p ,\ s\ a n d\ t are concurrent. Is always true that the lines q ,\ r\ a n d\ s will be concurrent? Is it always true for lines q ,\ r\ a n d\ t ?

Limes p,q and r are concurrent . Lines q,r and s are also concurrent . Will all the four lines p,q,r and s be concurrent ?

Lines p ,\ q are coplanar. So are the lines p ,\ r . Can conclude that the lines p ,\ q ,\ r are coplanar?

Find the coordinates of points P ,\ Q ,\ R\ a n d\ S in Figure.

The lines px +qy+r=0, qx + ry + p =0,rx + py+q=0, are concurrant then

The lines px +qy+r=0, qx + ry + p =0,rx + py+q=0, are concurrant then

Assertion: Number of triangles formed by n concurrent lines and a line which is parallel to one of the n concurrent lines is "^(n-1)C_2. Reason: One and only one triangle is formed by three lines out of which 2 are concurrent and third line is not passing through the point of intersection of the concurrent lines and not parallel to any of the concurrent lines. (A) Both A and R are true and R is the correct explanation of A (B) Both A and R are true R is not the correct explanation of A (C) A is true but R is false. (D) A is false but R is true.

If lines p x+q y+r=0,q x+r y+p=0 and r x+p y+q=0 are concurrent, then prove that p+q+r=0(where, p ,q ,r are distinct )dot

If lines p x+q y+r=0,q x+r y+p=0 and r x+p y+q=0 are concurrent, then prove that p+q+r=0 (where p ,q ,r are distinct ) .

In Figure, P\ a n d\ Q are centres of two circles intersecting at B\ a n d\ C. A C D is a straight line. Then, /_B Q D=
