Question

How to find the vertex, focus, directrix and latus rectum of the parabola?

Answer 1

hey mate here is your answer

Mark the two points on this line that are the same distance from the focus as the focus is from the directrix. You can use a compass to do this. Label the line connecting these two points 'focal chord'. The endpoints of the focal chord and the vertex are three of the points lying on the parabola.
