Concurrent Lines

In the adjoining figure (a) Name (i) Parallel lines (ii) all pairs of intersecting lines. (iii) concurrent lines. ( b) State whether true of false. (i) points A,B and D are collinear. (ii) lines AB and ED intersects at C .

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.
