Mathematics
From the adjoining figure, write
(i) all pairs of parallel lines.
(ii) all pairs of intersecting lines.
(iii) lines whose point of intersection is E.
(iv) collinear points.
Answer
(i) Parallel lines are lines that never meet.
∴ The pairs of parallel lines are l, m.
(ii) Intersecting lines are lines that cross each other.
∴ Pairs of intersecting lines are l, n; l, p; m, n; m, p; n, p.
(iii) Two or more lines whose point of intersection is E.
∴ Lines l and p intersect at E.
(iv) Collinear points are points lying on the same line.
∴ The collinear points are A, B, C ; A, E, D .
