                           lesson(3) Understanding Protractors
                                  lesson(4) Measuring angles

   ? Naming angles :
         ? Angle BAC is written as ( ? BAC)
         ? Its sides are AB and AC .
         ? Point A is called the vertex.

Note :                              A                           c

        is an angle symbol read as angle

Example: name the rays , the vertex and angles ?

                   1) The Rays are : XY , YZ

                   2) The Vertex is Y

                   3) The angles :

                       - Angle Y ,?Y

Y                                       - Angle XYZ , ?XYZ
                   Z - Angle ZYX , ?ZYX
