Write the converse of the following satement: If the two lines are parallel, then they do not intersect in the same plane.

The converse of the statement If two lines are parallel , then they do not intersect in the plane is

Lines are parallel, if they do not intersect' is stated in the form of

Write the contrapositive and converse of the following statements.(i) If x is a prime number, then x is odd.(ii) If the two lines are parallel, then they do not intersect in the same plane, (iii) Something is cold implies that it has low temperature.(iv) You cannot comprehend geometry if you do not know how to reason deductively.(v) x is an even number implies that x is divisible by 4.

Write the contrapositive of the following statements: (i)If x is prime number then x is odd (ii)If two lines re parallel then they do not intersect in the same plane. (iii) x is even number implies that x is divisible by 4.

Write the converse of the following statements: (i)If two integers a\ a n d\ b are such that a > b then a-b is always a positive integer. (ii)If x is prime number, then x is odd. (iii)If two lines are parallel, then they do not intersect in the same place.

Write the mechanism for following conversion:

If there are nine straight lines of which five are concurrent at a point and the other four are concurrent at another point and no two of these nine lines are parallel, then the number of points of intersection is equal to

Write the negatin of each of the statement : Two lines are parallel if and only if they have the same slope.

State which of the following statements are true (T) or which are false (F) If two lines in the same plane do not intersect, then they must be parallel. Distance between two parallel lines is not same everywhere. If m_|_l ,\ n\ _|_\ l and m\ !=n , then m n Two non-intersecting coplanar rays are parallel. No two parallel segments intersect. Every pair of lines is a pair of coplanar lines. Two lines perpendicular to the same line are parallel. A line perpendicular to one of two parallel lines is perpendicular to the other.

X -axis is the intersection of two planes.
