The triangle formed by the tangents to a parabola y2=4x at the ends of the latus rectum and the double ordinate through the focus is
Open in App
Solution
The correct option is D right-angled isosceles
Slope of tangent is given by 1t
At latus rectum t1=1
on other end t2=−1
Product of slopes =−1
Thus the triangle formed will be isosceles and right angled
Option C
Slope of tangent is given by 1t
At latus rectum t1=1
on other end t2=−1
Product of slopes =−1
Thus the triangle formed will be isosceles and right angled
Option C
