Parallel lines

ABCD is a rectangle. overline (AC) and ‘overline (BD) are diagonals. Write the pairs of parallel lines, perpendicular lines and intersecting lines from the figure in symbolic form. a) Parallel lines, b) Perpendicular lines, c) Pair of intersecting lines.

Assertion (A) : If 5 parallel lines intersect 4 parallel lines, then the number of parallelograms formed is 80 Reason (R) : The number of parallelograms formed when a set of m parallel lines are intersecting another set of n parallel lines is ""^(m)C_(2)xx""^(n)C_(2) The correct answer is
