Answer» Correct answer is (a) angle at which TWO PLANE reflectors are JOINED To explain I WOULD say: A CORNER reflector consists of two plane reflectors joined at a corner to allow radiation in forward direction only. Included angle is the angle at which two reflectors are joined, measured at the corner.
