No. of square rectangle parallelogram formed when m parallel & n parallel line intersect

The number of parallelograms that can be formed from a set of four parallel lines intersecting another set of three parallel lines is:

The number of parallelograms that can be formed form a set of four parallel lines intersecting another set of three parallel lines is 6 b.9 c.12 d.18

Intersecting and parallel lines

The angle bisectors of a parallelogram form a rectangle.

The angle bisectors of a parallelogram form a rectangle.

Assertion: If m parallel lines are intersected by n other parallel llines, then the number of parallelograms thus formes is (mn(m-1)(n-1))/4 , Reason: A selection of 4 lines 2 form m parallel lines and 2 from n parallel lines givers one parallelogram. (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 te correct explanation of A (C) A is true but R is false. (D) A is false but R is true.

Two non - parallel line segments will always intersect.

Assertion: Every rectangle is a parallelogram. Reason: Rectangle satisfies all the properties of parallelogram as opposite sides are equal and parallel, diagonals biseect each other and opposite angles are equal.
