The straight lines x−11=y−22=z−33\frac { x - 1 } { 1 } = \frac { y - 2 } { 2 } = \frac { z - 3 } { 3 } and

x−12=y−22=z−3−2\frac { x - 1 } { 2 } = \frac { y - 2 } { 2 } = \frac { z - 3 } { - 2 } are

A

Parallel lines

B

Intersecting at 60∘60 ^ { \circ }

C

Skew lines

D

Intersecting at right angle

Answer

Intersecting at right angle

Explanation

Solution

Since

Hence lines are intersecting at right angles.
