Two lines not lying in the same plane are called (A) parallel (B) coincident (C) interesecting (D) skew

If a pair of linear equations in two variables is consistent, then the lines represented by two equations are (a) intersecting (b) parallel (c) always coincident (d) intersecting or coincident

Which of the following statements are true (T) and which are false (F)? Give reasons. (i)If two lines are intersected by a transversal, then corresponding angles are equal. (ii)If two parallel lines are intersected by a transversal, then alternate interior angles are equal. (iii)Two lines perpendicular to the same line are perpendicular to each other. (iv)Two lines parallel to the same line are parallel to each other. (v)If two parallel lines are intersected by a transversal, then the interior angle on the same side of the transversal are equal.

The lines 6x=3y=2z and (x-1)/(-2)=(y-2)/(-4)=(z-3)/(-6) are (A) parallel (B) skew (C) intersecting (D) coincident

The lines 6x=3y=2z and (x-1)/(-2)=(y-2)/(-4)=(z-3)/(-6) re (A) parallel (B) skew (C) intersecting (D) coincident

Two parallel lines lying in the same quadrant make intercepts a and b on x and y axes, respectively, between them. The distance between the lines is (a) (ab)/sqrt(a^2+b^2) (b) sqrt(a^2+b^2) (c) 1/sqrt(a^2+b^2) (d) 1/a^2+1/b^2

If A(veca),B(vecb),C(vecc) and D(vecd) are such that 3veca+8vecb=6vecc+5vecd then the lines AB and CD are (A) parallel (B) intersecting (C) skew (D) none of these
