What is Latus Rectum of Parabola?

A) line segment B) vertex
C) focus D) major axis

Answer:   A) line segment



Explanation:

As parabola is a locus of a point, which moves so that its distance from focus and directrix is always equal.

The length of a parabola's latus rectum is 4p, where p is the distance from the focus to the vertex.
