Question

The line which passes through the focus and perpendicular to the major axis is ________

(a) Minor axis

(b) Latus rectum

(c) Directrix

(d) Tangent

This question was posed to me by my college professor while I was bunking the class.

This is a very interesting question from Construction of Ellipse topic in chapter Geometrical Construction of Engineering Drawing

Answer 1

Correct choice is (b) Latus rectum

To elaborate: The line bisecting the major axis at right angles and terminated by curve is called the minor axis. The line which passes through the focus and perpendicular to the major axis is latus rectum. Tangent is the line which touches the curve at only one point.
