- from the angle of information activities 1 teachers students observed a corner and answer as follows:
angle 1 และมุ group 2 anything either. (containing the same is a vertex angle and the arm of angle)
.1 corner angles and 2 anything different (name of angle is not the same size unequal angle)
angle 1 angles and angle 2 is same kind? (according to students' learning experience)
.There any way to help in the identification of the corner (according to the learning experience of students)
. The teachers and students together to check the accuracy of the answer!- teacher introduce more. In the absence of students presents the classification of angle in the same way as a teacher. We can use the right angle to angle measurement of various sizes, and classify those that corner angle of any kind.The measuring of angle, and make students build paper angle different 1 one
.- the student representative 3 people. Out to make angles with various sizes. And write the name of each corner, directed 1 angle, on the board, then the teacher to student 3 representative. Measurement of angles on the board out by using paper angle itself folded at a time 1 people.1 angle, then describe the characteristics of the measured angle. Write the name of the angles and the kinds of angles on the board, for example
