The triangle formed by the lines whose combined equation is `(y^2 - 4xy - x^2)(x + y - 1) = 0` is

A

equilateral

B

right angled

C

isosceles

D

obtuse angled

Text Solution

Verified by Experts

The correct Answer is:
B
The equations of the sides of the triangle are given by `y^2-4xy-x^2=0`
and `x+y-1=0`
Clearly, `y^2-4xy-x^2=0` represents a pair of perpendicualr lines.
Hence , the triangle is right angled.
