# NCERT Solutions for Class 11 Maths Chapter 10 Exercise 10.2 Conic Sections - PDF Download

NCERT solutions for class 11 maths chapter 10 exercise 10.2 Conic Section explains the concept of a parabola. A parabola is defined as the set of all points in a plane that are at the same distance from a single fixed line and a single fixed point within that plane. The students will also be learning about another new concept called the 'latus rectum' of a parabola. These concepts are defined in the proper way by subject experts of eSaral.

Class 11 maths chapter 10 exercise 10.2 NCERT solutions is composed of 12 questions in which some of the questions are short answer types and some of which are long answer questions.

## Topics Covered in Exercise 10.2 Class 11 Mathematics Questions

Ex 10.2 class 11 maths chapter 10 talks about parabola, its standard equations of parabola and latus rectum. You will be learning here a detailed explanation of these topics provide by expert team of mathematics at eSaral.

 1 Parabola 2 Standard equations of parabola 3 Latus rectum
1. Parabola - A parabola is the set of all points in a plane that are equidistant from a fixed line and a fixed point (not on the line) in the plane. The fixed line is called the directrix of the parabola and the fixed point is called the focus. The focus is represented by ‘F’.

A line through the focus and perpendicular to the directrix is called the axis of the parabola. The point of intersection of the parabola with the axis is called the vertex of the parabola.

1. Standard equations of parabola

The equation of the parabola with focus at (a, 0) a > 0 and directrix x = – a is

y2 = 4ax

1. Latus rectum

Latus rectum of a parabola is a line segment perpendicular to the axis of the parabola, through the focus and whose endpoints lie on the parabola.

Length of the latus rectum of the parabola y2 = 4ax is 4a.
