A quadrilateral is inscribed in a parabola. Then

A

the quadrilateral may be cyclic

B

diagonals of the quadrilateral may be equal

C

all possible pairs of adjacent sides may be perpendicular

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A, B
1,2
As a circle can intersect a parabola at four points, the quadrilateral may be cyclic.
The diagonals of the quadrilateral may be equal as the quadrilateral may be an isosceles trapezium.
A rectangle cannot be inscribed in a parabola. So, option (3) is wrong.
