From Figure, write
(i)Lines intersecting at `A`
(ii)Lines intersecting at `B`
(iii)Concurrent lines and their point of concurrence.

From Fig., write concurrent lines and their points of concurrence.

From the adjoining figure , write? (i) Collinear points (ii) Concurrent lines and their point of concurrence.

From the given figure, write (i) all pairs of parallel lines (ii) all pairs of intersecting lines (iii) concurrent lines and point of concurrence (iv) collinear points

Define the following terms: Concurrent lines

In the adjoining figure write. (i) all pairs of parallel lines (ii) all pairs of intersecting lines. (iii) Concurrent lines. (iv) Collinear points.

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.

Form Fig., write (i)all pairs of parallel lines. (ii)all pairs of intersection lines. (iii)lines whose point of intersection is l . (iv) lines whose point of intersection is D . (v) lines whose point of intersection is E . (vi) lines whose point of intersection is A .

From Figure, name (i)All pairs of parallel lines. (ii)all pairs of intersecting lines. (iii)ines of whose point of intersection in P (iv)lines whose point of intersection in C (v)lines whose point of intersection in R (vi)Collinear points.

In the figure alongside. Point M is called both the point of intersection and the point of concurrence.
