JEE Advanced 2020 Mathematics question
Let and be the following straight lines.
: = = and : = = .
Suppose the straight line
L: = =
lies in the plane containing and , and passes through the point of intersection of and . If the line bisects the acute angle between the lines and , then which of the following statements is/are TRUE?
Answer: (A),(B)
Solution
Both lines pass through , which is their point of intersection. Direction vectors: , , each of length . , so the angle between these two vectors is acute and the bisector of the acute angle is along $ +
