**Angles:-**

Angles are made when corners

are formed.

Here is a picture

where the top of a box is like a

hinged lid. The edges AD of the

box and AP of the door can be

imagined as two rays AD. These two rays have a

common end point A. The two rays here together are said to form an angle.

An angle is made up of two rays starting from a common end point.

The two rays forming the angle are called the arms or sides of the angle.

The common end point is the vertex of the angle.

(a) (b) (c) (d) (e)

This is an angle formed by rays OP

How can we name this angle? We can simply say

that it is an angle at O. To be more specific we

identify some two points, one on each side and the

vertex to name the angle. Angle POQ is thus a better

way of naming the angle. We denote this by

∠POQ.

Think, discuss and write

Look at the diagram.What is the name

of the angle? Shall we say∠P ? But then which

one do we mean? By ∠P what do we mean?

Is naming an angle by vertex helpful here?

Why not?

By ∠P we may mean ∠APB or ∠CPB or even

∠APC! We need more information.

Note that in specifying the angle, the vertex is always written as the

middle letter.

Now shade in a different colour the portion

of the paper bordering BC

The portion common to both shadings is

called the interior of ∠ABC. (Note

that the interior is not a restricted area; it

extends indefinitely since the two sides extend

indefinitely).

In this diagram , X is in the

interior of the angle, Z is not in the interior but

in the exterior of the angle; and S is on the

∠PQR . Thus, the angle also has three parts

associated with it.
