UNIT 2
Open the Angle Maker at three different positions and trace the angles formed.
An angle is formed when two lines meet.
The two lines meet at a point called a vertex.
An arc is usually used to represent the angle.
We can label the angle by a letter (e.g. a, b, c, ….)
1. Refer to Activity 3. Label all the angles that you have formed.
