The word angle comes from the Latin word angulus, meaning "a corner". The word angulus is a diminutive, of which the primitive form, angus, does not occur in Latin. Cognate words are the Greek meaning "crooked, curved," and the English word "ankle”. Both are connected with the Proto-Indo European root *ank-, meaning "to bend" or "bow"

When two lines intersect each other at a common end point is called angle.

Types of Angle Acute angle Right angle Obtuse angle Straight angle Reflex angle

ANGLE

An angle which measures 90 degree is called right angle.

Right angle

An angle which measures less then 90 degree is called an acute angle.

Acute angle

An angle which measures greater then 90 degree is called an obtuse angle.

Obtuse angle

An angle which measures 180 degree is called straight angle.

Straight angle

An angle which measures greater then 180 degree is called reflex angle.

Reflex angle

To learn about angles. By the end of the lesson the students will

identify the different types of angles.

Objectives

Teacher will assess the students by quiz or worksheets.
