The locus of a variable point which forms a triangle of fixed area with two fixed points is
Options
- Aa circle
- Ba circle with fixed points as ends of a diameter
- Ca pair of non parallel lines
- Da pair of parallel lines
Correct answer
D. a pair of parallel lines
Step-by-step solution
Let C be the variable point and A ; B be two fixed points. Area of ABC = 1 2 AB Height As A B is fixed. So, for constant area height should remain same, which is only possible if C moves on a line parallel to A B So, locus of C is a pair of parallel lines.
