Question

If a flagstaff subtends equal angles at four points a b c d on the horizontal plane through the foot of the flagstaff then the four points are

Answer 1

Answer:Cyclic Quadrilateral

Step-by-step explanation:

Answer 2

a , b , c & d are cyclic points

Step-by-step explanation:

a flagstaff subtends equal angles at four points a b c d on the horizontal plane through the foot of the flagstaff

Tan (angle) = Height of Flagstaff / Distance of point from Base of flag staff

as Angle is same  & height of flagstaff is same

hence Distance of point from Base of flag staff for a  , b , c & d is same

=> Distance of all four point abcd  is same

We can say that base of flagstaff is center of circle

& Distance of points a , b , c , & d from Base of flagstaff is radius

Hence a , b , c & d are cyclic points
